PHILADELPHIA (CBS) — "It was a stunning spring Saturday afternoon in Philadelphia with lots of people taking all in outside, making it impossible in some spots to maintain six feet of social distancing. Many people who did leave home were met with a gentle warning from roving trucks featuring the police commissioner’s voice blaring through the loudspeaker.
City leaders say the goal of those roving trucks isn’t to be threatening but to push people to do their part in flattening the curve.
Three mobile billboards drove around the city on Saturday, making stops in busy areas such as Rittenhouse Square. Residents saw and heard the mobile billboards from 11 a.m. until 7 p.m."
