I work in the area. Between Allisonville Road and Oleo Road on 116th there is usually quite a lot of police patrols during the day. It's easy to go above the posted speed limit on those roads. Most of it is 40 mph and it has 2 lanes in either direction. They are usually using Ka band but I've been hit with K also.
They use normal marked cars but also have an unmarked silverish firebird, a black Ford F150 and a dark colored Dodge Charger.
