Official plastic ammo can hidden among the rocks not too far down from the Plymouth Mtn trail. Some bush whacking may be required in the Summer. Should be an easy find.
Congrats to sassydil for FTF :-)
This is part of a series of full size caches hidden on or near to the route of a brutal Half Marathon. There are 7 in total + a bonus mystery cache (#8). Kudos to anyone who completes in one pass while running. Coordinates for the bonus can be found by putting together the clues found on the side (and bottom) of each cache in the series. You will need to find each cache to solve the puzzle: N39 32.ABC W105 D.EFG. The logical order if you want to do in one trip is probably: #3, #1, #2, #5, #4, #6, #7, #8.
