From Raleigh to Virginia is not far, and Virginia has some good MX tracks. Birch Creek in Danville, Va, run motocross and TT with Mid-Alantic and Southern ATV. Birch Creek also hosts the TT Nationals in April.
You are moving into an area that is seeing tremendous growth in racing. Virginia International Raceway will be hosting numerous motorcycle races in 2001, including an AMA Superbike race in September. I expect VIR to build a motorcross track and get some AMA National races.

Good Luck,
