On Maple Island, near the Muskegon County/Ottawa County bord
The unmarked Ottawa County Sheriffs like to sit on the east side of the road, on the Ottawa side near the Ottawa County/Muskegon County border. They are typically in an unmarked car, and it will look like a car is sitting back on the side of the road for sale (which there are a lot of them on this road). It is 55 through there, and they will get you for 1-2 over. Be careful. There is a 1-2 mile stretch, and they have several spots on both sides of the road.
