There's a privately owned area in Sneedville called Chinquipin (sp?) Off-road. They ride there every few weeks or so, I've yet to get down there but I hope to soon. They say there's not really any trail-riding there, just class 4-5 rockcrawling.
I've seen pictures and video, the place looks awesome.
And welcome to the area, there's several wheelers around here. Check out the website in my sig. We've got a lot of members in the area, and several from all over the country. We're growing every day too. You'll be hard pressed to find a better group of people to wheel with.
