Good luck! Seems that most people just don't seem to be able to read and understand signs no matter what they are for, stop, speed limit, or bike or off road trails closed (most are probably highly educated). Drove through the parking lot at Illiniwek yesterday and even with the sign saying the bike trails are closed there were two trucks in the lot one with a large FORC sticker in the back window:-/! Sign says the bike trails are CLOSED and that's just what it means.
