Last weekend we got away for a one night camping trip to Natural Falls State Park, in N. E. Oklahoma. Some really nice hiking trails with bluffs and scenery I didn't expect. Some of the filming of "Where the Red Fern Grows" was also done here. It's a small campground, no swimming or boating, but well maintained. There is a playground for the kids, and a fishing pond if you are up for a half mile hike.
