I have some small dents from Uwharrie, most are from Big Creek (first full size other than JC to go through the trails!), some are from the Flats.
Uwharrie and Grand Overland District would both be fun with a stock Power Wagon! We've had my 4th gen at Uwharrie several times (stock and modified (and umm... "clearance enhanced") and had some stock and modified 3rd gens (and Whitey's very modified and VERY "clearance enhanced" 3rd gen, LOL!) out there as well. There is definitely a tendency for eastern trails to be tight and technical but, wheeling a whale can be done! Heck, mine was on the trails with 100 or so miles on it on the third day I had it, fresh off the showroom floor! (for the iced/snowed over January 2013 Uwharrie workday)
