PITTSBURGH — Newly elected Pittsburgh Mayor Corey O’Connor strolled into Big Jim’s — a dimly lit shot-and-a-beer bar that doubles as a neighborhood restaurant in an area called “the Run,” an Appalachian term for localities adjacent to a stream, places often driven over but not usually seen by the general public. This one, in the lower Greenfield neighborhood where O’Connor’s father — the late Pittsburgh Mayor Bob O’Connor — lived, is no different. Commuters leaving work in the city zoom home overhead on Interstate 376.
