When heading toward Palmyra on East Derry Road, just after you pass the Hershey Country Club they like to place an orange (surprisingly hard to notice if you’re not looking) battery pack on the shoulder of the road to power a through beam sensor system. You will never see the police until it’s too late. Once they set up for the day, they’ll tag car after car. Maybe out of respect for the club, they seem to concentrate on traffic heading toward Palmyra.
