Police will sit in Hope High School parking lot(way in the back, so as to be unseen) and nail anyone doing over 30. Speed limit here is 25. Speed limit is not necessarily unrealistic, but this is what amounts to a main road, heavily traversed because of the woodlawn overpass crossing 70. O fallon police regulary stop older or beat-up looking vehicles, and will very often ask to search vehicle, with little to no reason. The sure fire to avoid this? SLOW DOWN!
