Jeff, unlikely for this group.
AFAIK, only sanctioned racing clubs have been getting access. And those are paying $50,000/day to operate the facility. If one had an SCCA legal race car, and a license, SCCA has an event there 3/8-3/10 .. entry fee is $650.
The vintage racing club SVRA and maybe CVAR will get there in Nov 2013, but again .. you have to be a member of a sanctioned club and have a prepared race car.
