Great area, located on Wagon Hill Farm. Go ahead and bring your dog. The cache is fairly well hidden, so be patient, or perhaps take a break and enjoy the view. It is a Letterbox hybrid, so as you know, take something and leave something except the stamp and stamp pad.
2018 Update - Thanks to The Yellow Dog Project for allowing me to adopt this cache - which is the oldest letterbox in New Hampshire.
