Travelling North on County line rd (away from Philadelphia) just off of Bustleton. One officer will sit either on one of the very small side roads or on someone’s lawn in or out of an unmarked car and clock someone. He is just after the crest of the very first hill that you climb off of Bustleton. Officers will flag people into a development ahead. I’ve been hit with it once, and seen it many times. Usually mid-day and evening traffic. The speed limit is 30 MPH, and very hard to maintain on the wide road and steep hills.
