This is where I've been the past month and have had a blast. http://www.maliasmiles.com/tennessee/river-plantation.htm
I have to be in SC near Columbia soon, but will be back in TN in mid August. Will be exploring other campgrounds in different areas and access to the National Park, but I surely wouldn't mind coming back here at all at some point.
Any members nearby for a GTG here or somewhere else in TN
