Philadelphia, Day 2

They actually have a subway system here! I don’t think I knew that. But it’s one of those that doesn’t run between midnight and 5 a.m. Philly’s starting to get some press that it’s a true 24/7 city, but that’s either the real estate people’s PR people talking, or I’m in the wrong part of Center City, or both. There’s no one out at night but bums and ne’er-do-wells.
