The closest Q joints that I can identify are located in Elkin (which should only be about 15 minutes east of Roaring River). I don't know that all of these joints are still operating, but if you go to "google" and type in: ""Roaring River, NC" barbecue", it should come up with five restaurants that serve Q.

I sure hope that this helps. Hopefully, I'll be making a trip to that area of NC soon and can let you know how I rate the different joints - if they are still there.
