The Grassy Knoll trailhead is not too hard to find, but if
you have troubles, just get down to the river trail and look back
towards the stadium (away from the river) for a trailhead
sign along the blocked roadway. For those who still can't find it,
try N36° 34.826' W079° 22.579'
There may be several ways into and out of the cache site,
however, the "preferred" method is via the Grassy Knoll
trail. Avoid bush-whacking this one and enjoy the trail. It isn't
all that long, and the views available if you just take the time
are worth a looksee.
Cache is hidden in a 50-cal Ammo box (largish) with
Geocaching.com sticker on the outside. The cache is hidden fairly
well from plain site, but the cache coordinates should take you
right to it.
Good luck.
