Philadelphia Trip

We just got back home from a 5th grade field trip to Philadelphia. It was really interesting and lots of fun. We got to visit many of the important USA buildings including the Betsey Ross House. Then, of course, we had Philly cheese-steaks for lunch. We also got to do a little shopping at the gift shops. I got a miniature Liberty Bell and a Philly bracelet. They're something I'll always be able to remember the class trip to Philadelphia with! My favorite part of the whole (long!) day was getting to see the actual singing place of the Declaration of Independence and our Constitution. It was so cool to see the old-fashioned furniture and everything! The bumpy bus ride was around 4 hours, but I'm pretty sure it was worth the wait. Have you ever been to Philadelphia? If so, what was your favorite popular attraction?
