While mountain biking along the Goffstown Rail Trail, my son
PB&Geo and I found this thought-provoking place. We suspect we
know what it was once used for and thought it might be interesting
to hide a cache here so you can also discover this rather unusual
area.
The cache is a micro, of course!
Note: if you happen to follow the trail in from Henry Bridge Rd
you'll see a prominent No Trespassing sign; this doesn't apply to
trail use and simply means not to cross onto prison property. You
wouldn't want to mess with that razor wire anyway.
Good luck!
