What about some of the stuff in the Cohutta Wilderness in GA. I was trying to find a hiking trail map and couldnt but I found one that lists 4 ORV trails. Rocky Flats, Wilma Creek, Tibbs, and Tatum Lead, none of them is actually in the wilderness all right around it. Thats all I really know though. Maybe GA Cruisers would know more.
I think all are ATV only except Tatum Lead and it's very tame. Tatum is a single track along a ridge then drops into a valley and dead ends.
