If money wasn't a issue heres how I would do it.
1. Drag track built to NHRA specs.
2. 1.5 mile road course built to nasa/scca specs (if there is such a thing). if people want to roll race use the straight to do so.
3. 5 acres for trailers and prep work
4. ala strip mall for vendors 12 slots 2 set aside for food 1 for a dyno, and 1 for security/medical. the rest for preformace shops kinda like a gasoline alley type thing
5. 6 restroom facilities
6. a drag/track tower to monitor everything plus offices for staff.
7. 10 acre parking lot.
8.plus anything else I am missing.
oh since its slow at work here.
