Not dual sport related but Tellico related. I stayed in Tellico Plains Saturday night at Hunt's Lodge Motorcycle Campground,
http://www.huntslodge.com/ It is owned by Jack and Lori who are both riders and they have nice setup just a mile or so out of Tellico on 68. Nice clean restrooms and showers, covered pavilion and picnic tables, comfortable cabins with boot/glove dryers and covered parking for the bikes, laundry access, lots of level area for tent camping and bike parking, and all at reasonable prices.
I kicked back at the fire pit after my ride and caught up with email since they have wireless and my phone would actually work for the first time that day. It was a very pleasant stay.
