I have recently received a couple of invites for our club to participate in some track days:
Great Lakes Lotus Grattan Raceway Drivers School October 6-7.
The Lotus Club president has invited our club to participate in their drivers school event on October 6th and/or 7th. Additional information is located here, and you can go to this site for registration.
CMMC Club member Jim C. will be out there in his 1974 Lotus Europa..
Midwest F Body Association at Road America October 13-14.
Also if you are looking for something a little closer to home, there are regular local Auto-X events hosted by the Windy City Miata Club.
