I think it would have to be a very professionally run and built track to get anything other than local boys to come out.
Some guys in SC ( Westminster ) very close to NE. GA had some land donated by the county that they built a nice little track on. It started slow but, now attracts a decent crowd........ " of locals ". The few trucks that show are nothing fancy and local. They charge $10 to get in and $10 per pull. From what I've been told.... they've spent more than they've made.
If you're asking if pros would show, I think that takes a lot of money for purses.... not counting money spent just to have the track, a lot of planning and professionalism to pull it off.
Good luck !
