I have seen all three law enforcement agencies (Council Bluffs PD, Pottawattamie County Sheriffs, Iowa State Patrol) here, on the median. By the time you see them (eastbound) it’s too late, and they’ve nailed you. Excellent hiding place for them, due to the curve in the road. West bound, almost the same story, the speed limit drops down to 10 less than what you were doing on the Interstate, because you’re getting ‘close to town’, and if you’re not paying attention, you will get hammered.
