MASS is only doing one race at circleville this year and it happened a couple weeks ago.
There is going to be a 2 day race weekend in St. Louis on a go-kart track.
Also, if you get in contact with the Ohio YSR leauge they would let you guys go out on the track day before one of there schedualed races. It's like $10 and you get alot of time.
also, theres ESRA (East Scooter Racing Ass). I dont know what there go-kart tracks are but they might get you guys in somewhere.
