Great pics. Had some friends run into some booby traps on the west end of the K-trail a few years back. I am not sure where the Clayton trail connects but the word is the K-trail is closed basically west of the firetower.
A buddy and I were going to do ham radio field day at the firetower, but it's private property so I think I may try to talk him into doing it at the end of a trail in the Ouachita NF overlooking Broken Bow lake.
You are welcome to come if you are interested.
