Traveling north on 53 just as you pass under Euclid Ave, there is spot on the right hand side that the police sometimes sit at. The speed limit is 55 (like every where in the Chicago land area) but the prevailing speed is usually 70-75. They usually use KA band, but I have had Lidar detected before as well. I’m not sure how fast you have to go to get pulled over, but you should watch for that section.
