Here's some things to do while in Philly:
- If you like History: check out the Liberty Bell and the National Constitution Center.
- If your big on food: check out the Reading Terminal Market. Tons of different cuisine and eat a real cheesesteak. Pat's & Gino's are legendary. Be sure to heed the rules when ordering. Its either "wit" or "wit out". Also, if you've never had one "Eat a Ritas". It will change your thoughts on water ice completely. Also, you could go eat at a Steven Starr restaurant - fun places with good/interesting food:

- If your an animal lover: try the Philadelphia Zoo, one of the best in the country. If you still are interested in animals, you can take a quick ride across the bridge into Camden, NJ to check out the Aquarium.
-If you are into art:check out the world famous Philadelphia Art Museum, you can even run up the stairs like Rocky! Other museums, like the Franklin Institute (very cool, but can be over run with kids) or the Mutter Mueseum, owned by the College of Physicians of Philadelphia and has very weird medical artifacts (not for the squimish!)
- For sports, you can try to go see a Phillies game or catch a regatta.
There are also cute towns within the city to walk through such as Manayunk (said "Manny-unk"), Old City, and Chestnut Hill.
