Just a FYI. Northeastern Carolina is planning on building a 1/4 mile drag strip, a 5/8 asphalt track, and a 1/2 mile dirt track. Its only 11miles from the VA/NC border.
Here is a quote.
The Mid-Atlantic Motorsport complex will consist of approximately 300 acres, located on Highway 17 North, just 11 minutes from the VA/NC state lines. The plan is for a 1/4-mile drag strip, a 5/8-mile asphalt track and a 1/2-mile dirt track and will provide this area with racing events on Friday, Saturday and Sundays. Sanctioning for all 3 tracks will be sought through National Sanctioning bodies. Each facility will be able to seat approximately 5000 spectators.
Also to build a decent track like VMP it will run 6-8 million in start up costs. However a track like Richmond would probably run 1/4 to a 1/3 of that cost.

If this track IS built I don't think a track within 30 mins will fly.
