This shouldn't pose much trouble to locate, even in the winter.
Just park in the carpool parking lot at the exit (waypoint above)
and go from there. Enter the woods on the east end of the parking
lot. Be careful in the winter time that you don't slip; a few times
my feet almost slipped from under me in the snow while leaving the
cache location. In the summer, watch where you step when you enter
the woods; unfortunately the area by the parking lot is sort of
messy and some people... well, anyway. It gets cleaner by the time
you reach the cache location.
At the time of hiding, the cache contained a kid's book, clamp,
laser pointer, bag clip, magnetic scupture toy, and more, along
with a little something for the FTF.
