Kenny, I checked with CGArbee and will include part of his helpful response concerning the Uwharrie Forest.
I am planning on hosting a gathering this comming April... There are a couple of trails that can be done with a duece, but the majority of them are too tight to take one up.
I'll also be running a few rides on the local forest service roads since we have some folks who either have trailer queens that they don't want to take on the trails or who don't feel comfortable driving the more difficult trails that a duece could easily run.
I'll be posting details on the forum when I get them figured out.
Unfortunately, I don't know of any really good OHV areas in NC that are setup for something big. Everything that I know of is really designed around a Jeep or pickup sized vehicle.
Tarheel, let us know if something works out with Mr. Allison.
