Coming into Marvell from Little Rock on 49. The police have been parked on the outbound lane of the highway until they sight you.They may or may not flash the lights.Then abruptly they will speed around you,to get in front of you up the road. Do not make eye contact. I expect the radar is never turned off. If stopped, any and I mean anything can set them off. This is a main route from everywhere west of Marvell to the Casinos in Mississippi.They want to get the money first.
