CHP vehicle sits on the side of the road by a call box. CHP officer gets out of the car and waits for the cars as the higway makes a slight dog leg right. Trees on the right side of the road blocks the drivers vision. When the trees end, and you are cruising out into the open, you see the officer aiming his radar gun at the oncoming traffic. Too late; he’s got you on radar. They sometimes work in two’s or three’s.
