The posted speed limit is 25 but it’s a road designed to do 40 on (of which you can easily do 45 on). The police sit in the borough tennis court parking lot about mid-way down Old Mill next to railroad tracks. If you’re coming down Summit Avenue off 208 (the road name changes to Old Mill after it crosses Franklin Ave) there’s a slight left bend in the road which provides the police a hiding spot when they’re sitting in the borough tennis court parking lot. You don’t even realize they’re there until you’re almost on top of them as they sit back in the entrance to the tennis courts. They’ll let you get away with 30 but don’t go any faster than that. They’re mostly there during AM and PM rush hour during the week and occasionally on the weekends.
