Track is outside Chicago, Joliet Ill. Fun, probably cheap race, SCCA racers welcome. (ps, If its a closed wheel car, probably council will let it run.) For info - http://mcscc.org/events.php
I bet details will be out in March. Try Gary Weis who's competition director at this link. http://mcscc.org/contact.php . If I were to guess, they are holding an autocross during the day and will hold the enduro from maybe 5 to 8pm. They are a fun group to race with.
