Marked and unmarked units sit in driveway of park along south side of roadway and target motorists coming eastbound from IL59. Common sight is a blue or black unmarked Crown Vic pulling over those who can’t maintain the 35 mph limit coming down the hill. Marked units seem to use the driveway for breaks/paperwork…it’s the unmarked units that get all the action. The West Chicago city limits are just beyond the park driveway, so it’s their last chance to nail people. The police were pulling so many people over on this busy street that a local resident erected a "Private Drive" sign to deter the police from executing their traffic stops in their driveway.
