Squad cars park in the Utley Park parking lot next to Minnehaha Creek and shoot radar at the traffic heading east down the hill on 50th St not far from the Hwy 100 and 50th St exit. speed limit is 30 mph, but cars tend to pick up speed coming down the hill. (No residences on either side of the street.) This is an active speed trap that may be present at any time during the day and any season. At least once during the summer, they set up a "sting" operation with several unmarked cars parked in spots on 50th next to the park. Officers in plain clothes stand outside the squad cars with radar guns.
