this speed trap is a dandy! If you are traveling west bound on Riggs road, just after you cross Glenburn drive, on the north side of the street (to the right), after several trees, against a tall concrete block/brick wall that separates residences” backyards from the Riggs Rd traffic, a Maricopa County Sheriff’s Office marked patrol car with all lights off, waits for the unsuspecting. after the several trees,there is grassy knoll with no trees or shrubs were the patrol car parks. there are more trees a little bit west of the grassy knoll which makes this an excellent hiding spot for jonny law.
