Seeing this was resurrected I will post what we did. The National Corn Bread Festival is worth going to at least once in your life. We really enjoyed the festival and the corn bread competition but the tasting was the best part. It is sponsored by Lodge Cast Iron and they open the foundry for tours which was interesting to see the production process.
We ended up staying at the Chattanooga North KOA in Cleveland TN and we found that to be top notch. An unexpectedly nice campground and we thoroughly enjoyed our weeks stay there. I would use it again and can recommend it.
Sasquatch Farms is not full hookup yet and I NEED a full hookup because of the wife, She refuses to use the CG facilities so I have to be able to empty the tanks quite frequently. When Sasquatch Farm finally gets their septic system up and running I will look into staying there.
