Half Moon Bay, California Speed Traps
Speed decreases from 50 MPH to 40 MPH. 40 MPH sign has a large shrub a few hundred feet in front of it so its easy to miss the sign if you are not looking for it. No "40" markings on the road either.
East of the Ford Dealership, in front of Main St. Park subsidized housing. HMB cops also like to ticket people who roll stop signs.
Squad car hides along the shoulder near trees especially if there is some fog. Careful. The cars are somewhat inconspiciuos.
