This is a letterbox hybrid. Geocachers just sign the log. Letterbox folks bring a stamp along and stamp another log and then stamp their personal log with the stamp in the container. So please don't take the stamp as swag. Please leave in the container for the next letterboxer.
As you hike or bike around this park you can't help but notice that the Little Miami River runs through this at times.
That is why this cache is securing attached to the tree/logs in the lee of the tree.
