Charlie,
It would probably be hard to get folks up there on a Friday open track day, although that is always a possibility. I'm not sure how much they charge or what time of day it's open, but it might be worth looking into. The track is up near Rockford (about 90 minutes northwest of Chicago).
What sort of interest do we have in a Friday open track day at
Blackhawk Farms ?
For me, I enjoy the autocross races, as you run in your specific class and get official timing and trophies.
