If you are coming from the East on I-270, there is a KOA campground at Granite City, IL. I've stayed there several times and has decent tent camping sites at $25 per night. Decent showers. Take the last exit in IL and go south a few hundred yards to the stop light, turn left and go over the rr tracks, then look for the KOA sign within 50 yards on the right. It's back in a little but a decent place.
