Oakdale police officers like to sit down on Helmo Road where the speed limit is "30 MPH" and has "Radar enforced" signs all over it, even though the speed limit is very slow and should be at least 45. The cops will hide on all off the off streets a ways down so when you pass them your radar detector goes on after its too late. No visible signs of them show except sometimes when they sit at the stop signs and you can slow down, then 2 minutes later they realize you pass and hit you with the K band radar.
