Checking my map it appears that the unmarked car which was sitting and clocking everyone was sitting on Low Ln watching 13 South. A Bucks County Officer was sitting where you make a left for the Tullytown Exit. Unmarked was using something called Acutrack or something similarly named. Was told it’s alot like Vascar. From what I gathered they did this to ALOT of people today (1/27/06) (saw quite alot of cars pulled over when I got back on 13 after making a 30 min stop)
