State Trouper station in Williamson, that sets up multi speed traps between the towns of Williamson and Ontario, and they do move them around. They also have real time scanner technology. They look and stop for any type infraction like light out. Any excuse to stop and also check for drinking or driving impaired. Last week of month very active. There is not a trip taken down this 12 miles of Rt 104 without seeing one and/or has someone pulled over.
