living here in central pa if you stay off the major highways and interstates, which are boring anyway, i've gone weeks without seeing a cop of any kind. not to say they're not there. the locals use vascar because they aren't allowed to have radar. usually they will give you almost 15mph before they pull you over. if you see a white painted line across the road especially if there's another 100 feet or so further down the road, slow down. those are they're timing marks. good chance there's a local hiding nearby. also they use other marks. got it one time in a downpour. cop had a 2 liter soda bottle filled with water set up along the road as his mark.
