Community can exist in any place where two or more humans gather. Port Authority operator Jill Smallwood sees it at rush hour, as she drives the P1 route from downtown Pittsburgh to Swissvale and back again. As her bus gets crowded, Smallwood can’t see all the way to the back of the bus, so she’ll appeal to her riders, “Do we have any room in the back?” Most of the time, they make space for one more.
