Thompson Speedway, located in NE Conn., the first paved oval in the US, and the first permanent road course in the US may re-open the road course, which has not been used since 1978, when my parents were racing. I could never forget the vees getting air-bourne when coming back onto the oval.

I'm guessing the rental fee will be much less than Lime Rock.
