It starts near Clive, right before the Douglas Ave exit for I-35/80. and continues on to the 2nd Ave exit for I-35/80. Cops will station themselves daily during the course of 2 to 3 days usually on the weekend along the interstate. It usually involves 7 to 10 cops during this monthly speed trap. Be very aware, the cops that will pull people over don’t tend to be the normal and original Crown Vics. The ones to pull you over usually will be the Ford Chargers that Iowa received. There exists at least 3 of them: one white,gray,and black Charger. All three are hidden cops, they don’t possess the prominent lights on top of their cars, they possess the small light and siren. I drove to Dmacc for class one morning and got pulled over by one of these hidden cops. It was seemingly just a normal Ford Charger who was rushing to get to work, but I later found that it was a cop trying to edge me on to go above the speed limit (though I am still annoyed with that pullover). Besides that, Just be on the lookout for the telltale look of Ford Chargers. They will be more hidden than the normal and obvious Crown Vics.
