I was on a hike today with rragan, kittyshrink, and nozy nabor, and we noticed that the Edwards Loop Trail was devoid of caches. We passed a huge, beautiful oak tree along with some very large downed branches, and it seemed like a good spot for a cache, so I added one.
The park is open from 8 AM to sunset.
You are looking for a camo-taped peanut butter container. There is an unactivated FTF mini-travel-bug for the first finder. Happy caching.
