you are looking for an ammo can just off the hiking/biking trail called itchy scratchy. Just park by the small shack called bus camp.
This cache is located off part off the black trail, this segment of trail is called itchy scratchy. To retrieve the cache you will have to do a short hike to reach the gz. The only part of trail that is really thick is where the cache is actually at. This is one of my favorite trails to end my mountain bike ride on. Hope you have fun finding this cache!
