The only touring car track I know about that is running regular events in KY is in Louisville. You can get their information from the bluegrass hobbies Area tracks forum.

There is all also a small group of onroaders in Glasscow but not sure what theier schedule is or if they are still running. Their information is on the bluegrass site.
