I have lived in Champlin for 11 yrs. and know the speed limit is 55mph on 169. The cops do sit at the intersection at 169 & 117, I have passed by the cop many times at that intersection at speeds from 56-60 mph . I had seen people pulled over who drive very fast or aggressively and cops have pulled these drivers over while I've been on 169. I do travel 169 everyday to work and back home with problems. I do believe most people who get driving tickes are because of their bad driving or speeding . We have speed limits to make it safe for all. P.S. I have gotten a speeding ticket for speeding. And I was speeding. Now I watch my speed.
