I live close to Philadelphia (actually, between Philly and New York), and a couple of weeks ago I went tromping through Center City. Normally when I go I roam through the west part of downtown, hanging out around Rittenhouse Square. This time, I went through the eastern part, going down to South Street, one of the funkier areas of the city (Manayunk is another cool place). Though, South Street has changed. When I went there in the mid-90s, there was a seediness to it that made it vaguely sketchy–even with a Starbucks. Now, there are two Starbucks and Whole Foods. And the bookstore I used to wander through is now a clothing store.
