Vanessa spent the better part of a weekend researching all these spots, checking links, getting directions, and otherwise being #1. Below is an extensive list that she put together of museums, skate spots, historic Philadelphia, neighborhoods, and architecture. We have also tried to add some places of interest for children, and we'll try to find a couple of parks to add as well. In the meantime, start threatening to leave them in the jail if they misbehave (the jail and some other stuff is listed under other places of interest).
