I came here a couple days ago to see the Museum of the American Revolution. It alone makes Philly worth a visit. Among many other things, teaching a lot about the Revolution, they have Washington's Tent. No shit. It is cool. But I have found a lot of other stuff around here. The Constitution Center, Independence Hall, Jewish Museum, African American museum, Eastern Penitentiary, Independence Seaport Museum (better than I thought it would be), Christ Church, etc., etc. Lots of "Ben Franklin-focused" stuff. I went on a tour called the "Founding Fathers Tour of Philadelphia" and it was outstanding. The heart of the City is relatively compact, walkable, and it is both attractive and safe. Lots of great architecture to see, good restaurants, WaWa...what more can you ask. My ONLY gripe is the abundance of panhandlers. I think I was hit up about once every block while I was walking the City. I gave away about $10 and ran out long before I got back to my room. Maybe I look like a soft touch. Seriously, if you are in the neighborhood, you could spend some very enjoyable and informative time here in Philadelphia.
