Route 20 always has speed traps. Going Eastbound. There is usually a cop sitting in the brush before rte 31, next to Elgin mental. Also, there is usally an officer sitting on the exit ramp of rte 25. It is difficult to see him. Going westbound, there is usally a cop sitting on the ramp from the Mcclean exit and right before Randall Rd. The rule of thumb on 20 is, if you see one cop, there are usally more, so be careful. They will also run random traps, off of 31, where the cops sit at the top of the bridge or in lawnchairs and radar. There is usually a long line of cars sitting of the ramp, waiting to pull you over!
