Sault Sainte Marie, Michigan Speed Traps
This is on Easterday between Meridian and the exit/entrance to I-75/International bridge. About once or twice every 2 weeks they will have police cars sitting by the Norris Center (of Lake Superior State University) looking for seatbelts and speeders. They will usually have 4 or 5 cars there and as you come up the hill you usually cant see them, but when you crest that hill all you see is flashing lights from others pulled over. They will get you, and before you even know it.
