Going Westbound on 290 right after the exit for Thorndale/Elgin O’hare Exwy a cop will sit in the median opening and there’s usually at least 5 cop cars lined up facing westbound waiting for the cop in the median to radio to them who is speeding and who to pull over. There are times that I have seen 7 cars pulled over for speeding all at once. I usually don’t see this heading eastbound though.
