First, a plug for the Bangor City Forest:
If you haven't been there, you need to check it out! I've lived in the greater Bangor area for my entire life and never knew this place existed. The Bangor City Forest (PDF map - more info) is a 650-acre nature reserve with a system of trails totalling almost 10 miles long! It also provides access to the Orono Bog Boardwalk. You won't be disappointed!
You can access the Bangor City Forest via a parking lot at the end of Tripp Drive (located off Stillwater Ave. near the Bangor-Orono line).
The cache is an ammo box with the usual items. We adopted this cache as we already have another cache hidden in the forest. See: Dylexic's Nightmare" (GCJ938). There also are 3 letterboxes hidden in the forest.

Good luck and happy caching!
