NER-SCCA has been researching becoming a racetrack owner-operator, also. At one time they had a line on a site in Palmer MA, not too far off the Mass Pike.
Possibly this is the source of the Springfield area idea.
I'm unsure of the current status of the NER search - there will probably be an update at the annual meeting in January.
The idea is to find an adeqaute area to be used for multi-use; racetrack, soloII, and rallycross; and rent it to other groups to augment income (ie, BMWCCA, NESCC, FCSCC, NESIC?)
