This is my first cache. The hill where this cache is placed has many paths and paved roads. There should be no problem getting to the cache site. You will probably find many distractions along the way ... relics from the military installation that was active here until 1953. There are many old structures and emplacements to explore. I'd suggest that you take a flashlight and plan to spend some time.
Now to the cache. Although the signal strength is a bit weak due to tree cover, you should be able to get close enough with the coordinates. The cache is in a camouflage painted ammo container. The cache includes several nice goodies: A blank CD-R, a key ring, a Garfield PEZ dispenser, Some Hot Wheels cars, a fire starter kit, a key ring flashlight, and a variety of other things.
Good luck finding this one and enjoy your time at the park. Make sure to cover this up very well.
