This should be a fairly quick cace & dash. You can park within 10 feet of the cache and look fairly non-chalant whilst looking for it.
You are looking for a camo'd round tin about 5 inches in diameter and about 1.5 inches high.
I've stocked the cache with some custom made keychains. There is also a FTF prize of a geocaching.com hiking stick medalion.
PLEASE be sure to hide this back as well or better than you found it so it will be around for a long time. This is a busy area, so it should not be visible to any passer-bys.
