I work at ADP in Parsippany and the wife of a state trooper emailed the whole office that this summer the state cops are cracking down on speeders on the highways. Cops will now cruise the highways in unmarked cars. (from experience usually they are malibu's or crown vic's, with all four windows tinted black) The cars only will have one maybe 2 antennas so it will be harder to spot them on the road.
The following roads will be patrolled more heavily:
Turnpike, Parkway, 287, 78, 280, 80
I see 2-3 people pulled over on 287 everyday I drive on it, by unmarked cars.
