During the summer months I’ve seen where they will backup 4 or 5 sheriff’s on the east bound entrance on to 120 coming off of Milwaukee (Rt 21). They have one cop standing on the bridge clocking everyone heading east. You can’t see the squads because they’re protected by the hill and it’s difficult to see the copper standing on 21 with his gun clocking everyone and radio’ing in the speeders. Then you pass the bridge and see 3 or 4 people all pulled over down by the expressway entrance getting tickets.
