There is a good bit of American History in Philly.
Maybe next year we could entice you to the Annapolis regional, which is only an hour or so away from Washington DC, which has alot of FREE museums, like
The Air and Space Museum, which is about the coolest museum I've ever been too. Along with all the rest that DC has to offer.
Unfortunatly, I don't have much to say about things to do in the Garden State.
