Mostly a weekend trap but on occasion I’ve seen a week long sting during rush hours. One officer sits atop a bridge with the radar and you don’t tend to see him. He radios to 4 or 5 squads sitting along side the road about a 1/4 mile up and they pick you out of the crowd. When everyone gets their catch, the officer on the bridge moves to the other side and they get people coming the other way. Generally speaking, you have to be doing 70 to get looked at since everyone seems to be doing at least 65 on that stretch.
