I realize this is an older thread but....
I just came across this thread today and thought I'd offer my two cents. I live in Boone (work in Blowing Rock) and while I used to frequent Sampson (Richland's) in my old Jeep, I know it's gone. There used to be a lot of great places to wheel but are sadly closed. I run Brown Mountain occasionally, only two trails available but I can find things to do for 4-5 hours. There is also Patriot mountain in Valle Crusis. Last fall I went to Uwharrie for the first time and even though it was a 3 hour drive, it was more than worth it.... Hope this helps, see you around maybe.
