Bingo! And it's 10x worse if you have out-of-state plates. For some of the little towns where the local mine has closed, speed traps are the entire economic base of the community (Ely NV, I'm looking at you...)

63 in a 60? $150! Never mind that's within the margin of error. I was going to stop for the night - that's dinner, maybe a couple beers, a motel room, breakfast, tank of gas, & etc, all going into the local economy. But now instead I think I'll push on through to Vegas...
