We ended up going to Kisatchie, staying a night, then leaving in the morning when it was STORMING. All in all, fun trip! I saw some scorpions...didn't know we had those here!
I always pack a trash bag and my rain gear. It's a little heavy, but worth it when you need it.
We never saw much wildlife other than small things, no deer or turkeys, but we did have a wild horse visit us at night. Our buddy saw it while he was in his hammock.
