Part 1 of a 3 part series.
Philadelphia and Pittsburgh would probably be inextricably linked together even if history hadn't lumped them together into the same state. As it stands, though, we have a lot more than an ugly blue flag and a bunch of corrupted mountebanks in Harrisburg in common. Both cities fell hard from the heights of their industrial power. And today, both are experiencing rebirths as centers of health care and education, and attracting young adults hand-over fist as leaders in the national urban renaissance, and heavily leveraging their legacy urban design and industrial assets to do it. There's certainly plenty of demand for cross-Pennsylvania travel.
So why is it so hard to get there from here?
