With only 1 month to go in the ARRL NPOTA event and some free time this Thanksgiving weekend, Fred and I decided to hit the road with our Mobile HF Station to activate some new parks.    We activated two nearby parks, each less than 1 hour away from our home,  Lamprey Wild and Scenic River,  WR23, near Epping, NH, and Minuteman National Historical Park, HP27, near Concord, MA.    There were close to 900K QSOs made overall in the NPOTA program as of Thanksgiving day and we also wanted to help the cause to get to 1 Million NPOTA QSOs by year’s end.

On Saturday, we drove to Epping, NH, where we activated Lamprey Wild and Scenic River. It was a rainy day, but we still enjoyed the scenic drive along the river. We drove along the river until we found a place by the river to park and operate. The bands were not great, with a K-index of 4 and a high A-index. Despite the conditions, our activation was a success. We operated on both 20m and 40m SSB and made a total of 307 QSOs over 3 hours.

I work in Burlington, MA and often travel between Burlington and Waltham, MA for meetings.  Each time I passed by Lexington on I-95 I saw the sign for Minute Man NHP and thought it would be fun to do a NPOTA activation from there.  We activated the park on Saturday. We entered the park from the Concord, MA end and were pleasantly surprised to see some nice countryside in the middle of a suburban area of Massachusetts, not far from Boston.

We operated from a parking lot in the park from mid afternoon until dark.  The bands were a little better on Saturday and we were able to get 239 contacts into the log, mostly US but also worked stations from Spain, Jamaica, Aruba and Puerto Rico.

We have enjoyed activating 8 National Parks so far in the NPOTA event.  We are planning another activation between Christmas and New Years of multiple parks before the end of the event on December 31.

Fall Antenna Projects – A New Low-Band Receive Antenna System


NCC-1 Receive Antenna System Control Unit and Filters

NCC-1 Receive Antenna System Control Unit and Filters

Anita and I like to take advantage of the mild fall weather to do antenna projects at our QTH. We have completed two such projects this fall – the installation of a Two-Element Phased Receive System and a rebuild of the control cable interconnect system at the base of our tower.

NCC-1 Receive Antenna System Components

NCC-1 Receive Antenna System Components

Our first project was the installation of a DXEngineering NCC-1 Receive Antenna System. This system uses two receive-only active vertical antennas to create a steerable receive antenna system. The combination can work on any band from 160m up to 10m. We set ours up for operation on the 80m and 160m bands.

NCC-1 Receive System Antenna Pattern

NCC-1 Receive System Antenna Pattern

The NCC-1 System can be used to peak or null a specific incoming signal. It can also be applied to a noise source to null it out. The direction that it peaks or nulls in is determined by changing the phase relationship between the two Active Antenna Elements via the NCC-1 Controller.

NCC-1 Filter Installation

NCC-1 Filter Installation

The first step in the project was to open the NCC-1 Control Unit to install a set of 80m and 160m bandpass filter boards. These filters prevent strong out-of-band signals (such as local AM radio stations) from overloading the NCC-1. The internal switches were also set to configure the NCC-1 to provide power from an external source to the receive antenna elements through the connecting coax cables.

Installed Active Receive Antenna Element

Installed Active Receive Antenna Element

The next step in the project was to select a suitable location for installing the Receive Antenna Elements. We choose a spot on a ridge which allowed the two Antenna Elements to be separated by 135 ft (for operation on 160m/80m) and which provided a favorable orientation toward both Europe and Japan. The antenna elements use active circuitry to provide uniform phase performance between each element’s 8 1/2 foot whip antenna and the rest of the system. The antenna elements should be separated by a 1/2 wavelength or more on the lowest band of operation from any towers or transmit antennas to enable the best possible noise rejection performance.

Received Antenna Element Closeup

Received Antenna Element Closeup

The two Antenna Elements were assembled and installed on 5 ft rods which were driven into the ground. To ensure a good ground for the elements and to improve their sensitivity, we opted to install 4 radials on each antenna (the black wires coming from the bottom of the unit in the picture above). The Antenna Elements are powered through 75 ohm flooded coax cables which connect them to the NCC-1 Control Unit in our shack. The coax cable connections in our setup are quite long –  the longer of the pair being approximately 500 ft. The use of flooded coax cable allows the cables to be run underground or buried. Should the outer jacket become nicked, the flooding glue inside the cable will seal the damage and keep water out of the cable.

Receive RF Choke

Receive RF Choke

It is also important to isolate the connecting coax cables from picking up strong signals from nearby AM Radio stations, etc. To help with this, we installed Receive RF Chokes in each of the two coax cables which connect the Antenna Elements to the NCC-1. These chokes need to be installed on ground rods near the Antenna Elements for best performance.

Underground Cable Conduit In Our Yard

Underground Cable Conduit In Our Yard

We ran the coax cables underground inside cable conduits for a good portion of the run between the antenna elements and our shack. The conduits were installed in our yard when we built our tower a few years back so getting the coax cables to our shack was relatively easy.

Receive Antenna Coax Ground System

Receive Antenna Coax Ground System

The last step in the outdoor part of this project was to install a pair of 75 ohm coax surge protectors near the entry to our shack. An additional ground rod was driven for this purpose and was bonded to the rest of our station’s ground system. We routed both of the 75 ohm coax cables from the two Antenna Elements through surge protectors and into our shack. Alpha-Delta makes the copper ground rod bracket shown in the picture for mounting the surge protectors on the ground rod.

Antenna Equipment Shelf In Our Shack (The NCC-1 Control Unit Is At The Bottom)

Antenna Equipment Shelf In Our Shack (The NCC-1 Control Unit Is At The Bottom)

The installation work in our shack began with the construction of a larger shelf to hold all of our antenna control equipment and to make space for the NCC-1. The two incoming coax cables from the Antenna Elements were connected to the NCC-1.

microHAM Station Master Deluxe Antenna Controller

microHAM Station Master Deluxe Antenna Controller

Antenna switching and control in our station is handled by a microHAM System. Each radio has a dedicated microHAM Station Master Deluxe Antenna Controller which can be used to select separate transmit and receive antenna for the associated radio. The microHAM system allows our new Receive Antenna System to be shared between the 5 radios in our station.

Antenna Switching Matrix

Antenna Switching Matrix

The first step in integrating the Receive Antenna System was to connect the output of the NCC-1 to the Antenna Switching Matrix outside our shack. We added a low-noise pre-amp (shown in the upper left of the picture above) to increase the sensitivity of the Antenna System. The blue device in the picture is a 75 ohm to 50 ohm matching transformer which matches the NCC-1’s 75 ohm output to our 50 ohm radios. The other two pre-amps and transformers in the picture are part of our previously installed 8-Circle Receive Antenna System.

Multi-Radio Sequencer

Multi-Radio Sequencer

The Antenna Elements must be protected from overload and damage from strong nearly RF fields from our transmit antennas. In a single radio station, this can be handled via a simple sequencer unit associated with one’s radio. In a multi-op station such as ours, it is possible for a different radio than the one which is using the Receive Antenna System to be transmitting on a band which would damage the Receive Antenna System. To solve this problem, we built a multi-radio sequencer using one of the microHAM control boxes in our station. The 062 Relay Unit shown above has one relay associated with each of the five radios in our station. The power to the Receive Antenna System is routed through all 5 of these relays. When any radio transmits on a band that could damage the Antenna Elements, the associated relay is automatically opened 25 mS before the radio is allowed to key up which ensures that the system’s Antenna Elements are safely powered down and grounded.

NCC-1 Controls

NCC-1 Controls

So how well does the system work? To test it, we adjusted the NCC-1 to peak and then null a weak CW signal on 80m. This is done by first adjusting the Balance and Attenuator controls on the NCC-1 so that the incoming signal is heard at the same level by both Antenna Elements. Next, the B Phase switch is set to Rev to cause the system to operate in a signal null’ing configuration and the Phase control is adjusted to maximize the null’ing effect on the target signal. One can go back and forth a few times between the Balance and Phase controls to get the best possible null. Finally, the incoming signal is peaked by setting the B Phase switch to Norm.

Peaked And Null'ed CW Signal

Peaked And Null’ed CW Signal

The picture above shows the display of the target CW signal on the radio using the NCC-1 Antenna System. If you look closely at the lower display in the figure (null’ed signal) you can still see the faint CW trace on the pan adapter. The difference between the peak and the null is about 3 S-units or 18 dB.

NCC-1 Used For Noise Cancellation

NCC-1 Used For Noise Cancellation

The NCC-1 can also be used to reduce (null out) background noise. The picture above shows the result of doing this for an incoming SSB signal on 75m. The system display at the top shows an S5 SSB signal in the presence of S4 – S5 noise (the lower display in the picture). Note how clean the noise floor for the received SSB signal becomes when the unit is set to null the noise source which comes from a different direction than the received SSB signal.

We are very pleased with the performance of our new Receive Antenna System. It should make a great tool for DX’ing on the low-bands. It is a good complement to our 8-circle steerable receive system which we use for contesting on 160m and 80m.

Tower Control Cable Interconnects (Bottom Two Gray Boxes)

Tower Control Cable Interconnects (Bottom Two Gray Boxes)

Our other antenna project was a maintenance one. We have quite a number of control leads going to our tower. When we built our station, we placed surge protectors at the base of our tower and routed all of our control leads through exposed connections on these units. Over time, we found that surge protection was not necessary and we also became concerned about the effects that sunlight and weather were having on the exposed connections. To clean all of this up, we installed two DXEngineering Interconnect Enclosures on our tower and moved all the control cable connections inside them.

Inside View Of Interconnect Enclosures

Inside View Of Interconnect Enclosures

We began with a pair of enclosures from DXEngineering and we mounted screw terminal barrier strips on the aluminum mounting plates in each enclosure. The aluminum plates are grounded via copper strap material to our tower.

Closer Look At One Of The Interconnect Enclosures

Closer Look At One Of The Interconnect Enclosures

The picture above shows one of the interconnection boxes. This one is used to connect our two SteppIR DB36 Yagi Antennas and some of the supporting equipment. The barrier strips form a convenient set of test points for troubleshooting any problems with our equipment on the tower. There are almost 100 control leads passing through the two enclosures and this arrangement keeps everything organized and protected from the weather.

With all of our antenna projects complete, we are looking forward to a fun winter of contesting and low-band DX’ing.

NPOTA Fun – Activating a New Park


River 2

Eastern Branch of the Penobscot River in Katahdin Woods and Waters NM

Ever since we built our Mobile HF Station, we’ve talked about taking it to Acadia National Park in Maine and operating from the top of Cadillac Mountain.  The 2016 ARRL NPOTA event gave us the motivation to plan the trip for the week before Labor Day.    The week before our trip, we saw an article in the ARRL Letter encouraging operation from the newly declared National Monument, Katadhin Woods and Waters in Maine, which had just be designated as NPOTA MN84.  Visiting the NPS website, we learned that the park is only a 2 1/2 hour drive from Bar Harbor, where we are staying.  We decided to accept the challenge to be the first to activate the new park.

Mobile HF In Park 1

Our F150 Mobile Station at the entrance to Katahdin Woods and Waters National Monument

Tuesday August 30 was our first full day of vacation, we left our hotel room and parked by the Acadia visitor center and called “CQ National Parks”.   We ended up with 76 contacts in the log from NP01.

After that we got on the road and headed toward Katadhin Woods and Waters, activating counties along the way including the county line between Penobscot and Aroostook Counties.

MN84 Map

NPS Map of the Park

As a newly designated National Monument, Katadhin Woods and Waters does not yet have a visitors center or any signs showing you when you enter and exit the park.  We just had the map (above) to determine where the park boundaries were.    All of the roads in black on the map are gravel roads that are also used for logging trucks.

Katahdin Woods Sign 1

Entrance to Kadahdin Woods and Waters National Monument

We entered the park from Swift Brook Road off Rt 11 in the lower right corner of the map.  We drove through the lower section by the entrance and then headed north along the Eastern Branch of the Penobscot River and operated near the Loos camping area.   The sign above confirmed that we were within the park boundaries.

River 3

Scenic View of Katahdin Woods and Waters NM

The scenery along the river was beautiful with views of the mountains in the distance.

Mobile HF In Park 3

Operating at MN84

We started operating on 20m and the pileups were huge!  Everyone was excited to get this new NPOTA into the log.  Fred, AB1OC/M ended up going split on 20m due to the size of the pileups.  After a while, he moved to 40m to give the close in folks a chance at MN84.  We went back and further between 20m and 40m until the pileups thinned out.   We also made 18 QSOs with the club callsign N1FD to also give the club credit for the activation.  We really enjoyed activating the park and the people we talked to were great!  We made a total of 350 QSOs from MN84.

National Park Yes!

Friendly Sign at Katahdin Woods and Waters NM

We also plan to activate Acadia National Park NP01 again from Cadillac Mountain this week. We will also activate Saint Croix Island, HS01 and Roosevelt Campbello International Park, AA21 in Canada (as AB1OC/VE9 and AB1QB/VE9).

Activating MN84 for the first time was truly a memorable experience.  We enjoyed it so much we will be back on Saturday to give more NPOTA chasers a chance at MN84!  Hope to talk to you on the air!

Summertime Station and Antenna Projects At AB1OC/AB1QB


Summer is the time of year that many of us work on our antennas and improve our stations. Anita AB1QB and I did both of these things at our QTH this summer.

Removing Lower SteppIR Yagi From Tower

Removing Lower SteppIR Yagi From Tower

Our SteppIR DB36 Yagis were due for some maintenance so we took them off our tower. A special thanks to all the members of the Nashua Area Radio Club who helped us remove, recondition and reinstall our antennas! Matt Strelow, KC1XX of XX Towers and Andrew Toth provided equipment and know how to safely remove our two large SteppIR DB36 Yagis with help from the rest of us.

Lowering Antenna With Electric Winch

The SteppIR DB36 Yagis weigh almost 200 lbs each and Matt made good use of his electric winch to lower them.

Antenna Coming Down The Tram Line

The picture above shows the lower antenna coming off the tower. We used a Tram Line system to lower both antennas to the ground so that we could rebuild them.

SteppIR DB36 Antenna On The Ground

SteppIR DB36 Antenna On The Ground

The SteppIR DB36 Yagis are quite large. They have 36 ft booms and the driven elements are almost 50 ft from tip to tip! They completely fill up our back yard when they are both off the tower.

Element Pole Sun Damage

The rebuild process began with a careful inspection of both antennas. They were both in good overall condition with some sun damage to the paint on the fiberglass element poles.

Disassembled SteppIR DB36

We removed all the element tubes and sweeps from both antennas for rebuilding. The picture above shows the disassembled upper antenna.

Reconditioned Stepper Motors Installed

Reconditioned Stepper Motors Installed

All four Stepper motors on both antenna were replaced. These motors move metal tapes inside hollow element tubes to adjust the length of each antenna’s 4 movable elements. These adjustments are done automatically by controllers in our shack which receive frequency information from the radios which are connected to each antenna.

Reconditioned Element Sweep Poles

Reconditioned Element Sweep Poles

All of the element housing poles were cleaned, prepped and painted with a UV resistant clear coat to protect them from further sun damage. The poles cleaned up like new.

New Element Sweeps Ready For Installation

The assembly of all the new element sweep tubes (shown above) was done next. Each antenna has six sweeps.

Element Pole Preparation

Element Pole Preparation

The end of each element pole must be prepped with a tape system which ensures that the poles are seated properly, sealed to and firmly attached to the sweeps. This process and the associated assembly and tightening of the element couplers was the most time-consuming step in the rebuild process as it had to be repeated a total of 24 times.

Rebuilt Element Assembly

Rebuilt Element Assembly

Here’s a picture of one of the rebuilt element tube assemblies. The ropes support the element tubes and keep them aligned when the antenna is up in the air. These elements are attached to the antenna motors with couplers and clamps.

SteppIR DB36 Yagi - Rebuild Complete

SteppIR DB36 Yagi – Rebuild Complete

The picture above shows the lower antenna with all the element tubes reattached. There is quite a bit of additional prep work associated with adjusting all the supports and taping all the exposed areas of the antennas which are susceptible to sun damage. Also, all the electrical wiring on the antenna must be checked to ensure good electrical connections and good overall condition of the wiring.

Ground Test Setup

Ground Test Setup

The final step in rebuilding the antennas is to test their operation on the ground. This ground test is done to ensure that all the motors are working correctly and that the element tapes move smoothly inside the rebuilt element tubes.

Ground Test Results

Ground Test Results

Another important part of the antenna Ground Test is to confirm that the antennas have a consistent resonant frequency and SWR on all bands. The resonant frequencies and SWR levels are far from those that would be measured when the antennas are on the tower at operating height. The idea here is to confirm that a resonance exists and that its frequency and SWR readings are repeatable as the antenna is adjusted to different bands.

With both antennas rebuilt, its was time for Matt and Andrew to return and, with help from folks from our club, reinstall the rebuilt antennas on our tower. The video above shows this process. It is quite something to see! The installation took about 3 1/2 hours.

Updated SteppIR Controllers

Updated SteppIR Controllers

The last step in the SteppIR DB36 rebuild process was to install the latest firmware in the associated SDA100 Antenna Controllers. There are some integration issues between the updated SteppIR Firmware and our microHAM system but we are getting those worked out with help from the folks at both SteppIR and microHAM.

Icom IC-7851 With Display Monitor

Icom IC-7851 With Display Monitor

I recently had a major birthday milestone and Anita surprised me with a new radio – an Icom IC-7851. This radio is an upgrade/replacement for our Icom IC-7800. While the two radios are quite similar in their operation and interfaces, I did not want to install the IC-7851 until the SteppIR antennas were reinstalled and all of their upgrades were working properly with our current radios. With the antennas done, it was the finally time to install the new radio!

Icom C-7851 Transceiver

Icom C-7851 Transceiver

The Icom IC-7851 has several important performance upgrades. The most impactful one is a new low phase noise oscillator which significantly improves RMDR performance compared to the IC-7800. The IC-7851 is in the top-tier of Transceivers in Sherwood Engineering’s tests. The receivers in the IC-7851 are very quiet, have excellent Dynamic Range and perform great in when close-in interference is present.

Icom IC-7851 Display Monitor

Icom IC-7851 Display Monitor

The Icom IC-7851 has a higher resolution and faster display. It also supports higher resolution external monitors so we installed am upgraded display monitor along with the new radio. The IC-7851 has a number of new networking features and supports stand-alone remote operation over a LAN and the Internet. We are planning to use these capabilities to add a second remote operating gateway to our station. More on this in a future article.

The combination of the rebuilt antennas and the new IC-7851 Transceiver has our station performing better than ever. The antennas are working as well or better than when they were new and the IC-7851 has significantly better receive performance compared to its predecessor and is a pleasure to use.

We will be hosting the ARRL Rookie Roundup RTTY contest for our club members who have received their first license in the last 3 years next weekend and we’re going to use the new radio and rebuilt antennas for the contest.

This project was completed in a little over two weeks and was a lot of work. I could not have done the project without the help of the many folks in the Nashua Area Radio Club. Again, a big Thank You to all the folks in our club who helped me with this project! I hope that many of you will be able to find some time to operate from our upgraded station.

2016 Field Day Site Layout

I had the privilege of acting as the Field Day Incident Commander for the Nashua Area Radio Club this year. Field Day is the most important operating event for the Nashua Area Radio Club each year. We operated under our club callsign, N1FD and we were 7A here in New Hampshire, USA. We included some new antennas including a Three Element 40m V-Beam, a Satellite Station and a 70cm Digital ATV Station in our operation this year. You can see some of the details which went into the planning of our 2016 Field Day Operation on our Club’s Tech Night Page.

The video above shows highlights from our 2016 Field Day Operation. As you can see, we had a lot of fun at Field Day this year. Our club has 120+ members and we had a large turnout for Field Day. You can see more about our 2016 Field Day operation on our Field Day Page including photos, a score summary and a recap presentation shared at a recent club meeting. I hope that you enjoy sharing our memories from 2016 Field Day.

2016 New England QSO Party – Operating Mobile HF


Several members of the Nashua Area Radio Club operated as N1FD/M (our club callsign) in the New England QSO Party this year as a Multi-Op Mobile Entry. Operators included Wayne Wagner, AG1A and Jamey Finchum, KC1ENX and myself. We began our operations on Saturday afternoon on the Massachusetts – New Hampshire State line where we activated two counties and two states.

NEQP Multi-Op Team

N1FD/M NEQP Multi-Op Team

We entered the 2016 NEQP Contest in the High Power Multi-Op Mobile Category. We operated using SSB phone mode using mostly on the 20m and 40m bands. We took turns operating, driving and navigating. We used Fred’s, AB1OC’s mobile HF station in his truck.

CQ NEQP 4

CQ NEQP from N1FD/M

We operated Saturday and Sunday for nearly the entire contest period. We spent most of our time calling CQ and we had several nice pileups to work.

Counties Activated 2

Counties Activated by N1FD/m in the 2016 NEQP

The map above shows the counties in Massachusetts, New Hampshire and Vermont that we activated during the contest. Anita, AB1QB helped us to create a route of counties to activate which included some of the more rare counties in Vermont and New Hampshire.

Operating On The Line 4

Operating on a County Line in Vermont

We tried to focus on activations where we could be in two counties as once. These activations produced some nice pileups for us to work.

Operating On The Line 1

Operating on a County Line in NH

We parked on county lines with 2 wheels of N1FD/M in one county and 2 wheels in another. This gave us two QSO points (one for each county) for each contact that we made.

NOPTA Activiation 2

NPOTA Activation – Marsh-Billings-Rockefeller NHP in Vermont

We also activated two National Parks along our route as part of ARRL’s NPOTA program. We activated Saint-Gaudens NHS (NS60) in New Hampshire and Marsh-Billings-Rockefeller NHP (HP26) in Vermont. The HP26 activation produced the best response – we made about 50 contacts while we were there.

Solar Weather for NEQP

Solar Weather for NEQP 2016

We had a few challenges along the way. We had some antenna related problems to deal with. Fortunately, we had spare parts with us and we adjusted our operating style to overcome these problems. We also had to operate through a major solar event on Sunday. This made contacts very difficult but we still logged over 235 QSOs on Sunday in spite of the conditions.

CQ NEQP 1

Wayne, AG1A Operating in NEQP 2016

We used a PC running the N1MM+ logger connected directly to the Icom IC-7000 radio which is mounted on the passenger side lower interior panel in our truck. This made if very easy for whomever was operating to keep up with the logging when our QSO rates were high.

All in all, we had a great time in the contest. We logged a total of 631 QSOs and we worked 58 Multipliers. Our final claimed score was 36,598 – not bad given that this was our first entry as a mobile and our first time in NEQP. We worked 43 of 50 states and we had quite a few stations from Canada and Europe call in to answer our CQs. All in all, it was a lot of fun operating from our Mobile HF station in the NEQP contest!

There was some discussion on the way home about the Maine and New Hampshire QSO parties which will be held later this year. We hope to be N1FD/M again in one or more of those as well.

Dayton Hamvention 2016


Anita Preseting in Contest ForumFred, AB1OC and I just returned from the 2016 Hamvention in Dayton, OH.

Our first day in Dayton was spent at Contest University – this was our 5th year in attendance but each year we learn more from the contesting experts. This year, we attended two presentations from Frank Donovan, W3LPL on operating techniques for the declining solar cycle and on 80m and 160m antennas.   We also heard a talk from Val NV9L from Ham Nation on Log Analysis tools and another session on SO2R (Single Operator 2 Radio) Operating.

W3LPL Solar Cycle 5

Slide from W3LPL Contest University Presentation

Friday was the first day of the Hamvention and we spent most of the day visiting all of the vendor exhibits.   We visited the Icom booth, where we looked at the new Icom 7851. It has an incredible display as well as one of the best receivers on the market.

We also saw the new KX2 Transceiver at the Elecraft booth. It is even smaller than the KX3 and is perfect for SOTA and other portable operations. I would expect to hear some NPOTA activations using this radio.

Friday evening was the Top Band dinner where we learned all about “Top Band Disease” from Larry “Tree” Tyree N6TR.   Hams with this disease are nocturnal, love the bottom of the sunspot cycle. They are constantly improving their 160m antennas – when you upgrade your receive antenna, then there are people who can’t hear you, so then you need to improve your transmit antenna – and the cycle continues…

Top Band Dinner Presentation by N6TR

After the dinner, we were treated to a concert from the Spurious Emissions Band (N0AXKX9XK4ROW4PA), with hits like “On The Cover of the NCJ” and “Sittin on the Edge of the Band”. They were so funny! You can watch their performances on YouTube http://bit.ly/DaytonSpurs2016.

We also visited the AMSAT booth, where we met Burns Fisher,  W2BFJ,   who currently lives in Brookline, NH and is moving to Hollis.    They had a cube sat on display – you can see how small it is below.  It’s amazing that AMSAT builds and arranges to launch them into orbit so that we can make QSOs through them!

On Sunday, we headed back to New Hampshire, sad that the weekend had come to an end but full of great memories from the trip.
