There are a couple of tracks in NC. I have been to two of them. However, I am surprised that aren't any in the Raleigh-Durham-Chapel Hill area. It is hard to find a decent off-road track. There is one in Goldsboro and one in Sands Hill. There is one in Durham, but it is very very small and not much jumps. There is also a drag-strip that several people run at, (but I'm just not into drag racing).

There are a couple of other tracks, but they don't have any websites and they are way out in the rural parts of the state.

If you are serious about doing something, then central NC would be a good place. I think there is a good following in the area. The main problem around here is that there isn't a decent track to run at.
Seriously, I think that if you have an all-in-one place, then you will do good as a business. I would suggest:
--Off-road track
--On-road track
--Drag Strip
Plus, don't forget about a hobby shop where you should things like porting and polishing. You can even advertise it to the professional circuit and have some of the big national races held there.
Let me know if I can help out any.
