Haven't had a radar detector for over 30 years.
Neither have I. And I've had surprisingly few tickets considering my riding style.
Picked up my first ticket in 2 or 3 years last week. Just south of Houghton. 76 in a 55 but he wrote it for 5 over. $140. 
Apparently the law in WA state (acc'd to the state trooper) says that the vehicle's valid speed measurement can only be derived from the manufactured speedometer that came with the vehicle. Garmin speed is invalid. Of course this was his response when he learned that I depend on my 660's speedometer and not my bikes because my bike reads 8% faster than actual. Therefore, that was good enough for him to convince himself I was guilty, even though he uses continuous k-band and was accelerating over a hill at the time I was decelerating when the road became a long sloped straightaway and there was nobody in sight for at least 1000 yards.
The $300 spent on that ordeal should have gone into a radar detector.
