Thurs Aug 5 at 3:30 pm at the Mt. Airy train station. A car. A construction worker (Septa?) sitting inside. I observed idling here earlier this week or last week, also by a construction worker, who appeared to be sleeping inside his car, windows rolled up, AC on. (There's a project going on at the station.)
When I knocked on a window and spoke with him about the anti idling law, he turned off his motor and thanked me!
