JohnTee: Since this cache required the geocacher to leave the marked trail, this cache is going to be permanently archived. MO DC is very interested in placing caches on the nature center grounds, they will just have to be placed within the guidelines of not leaving the marked trail. A challenge indeed.
I'll be working with them to place two new caches in the near future, one handicapped accessible and one with a good hike, so keep watching the area.
Otherwise, this is a beautiful trail and nature center to visit.
