My boyfriend and I are taking a road trip to Reading, PA in October (we're going to the NHRA drag races out there) and are driving down. We're going to stop in Philly for the day on our way down and I need some idea of what we can see/do for the early afternoon-early evening. We'll probably get there around 11-12 and will take off again sometime before it gets too dark (I'm hoping we can stay past rush hour and have dinner there too, but we'll see). Any suggestions?? I've been to Philly years ago and did all the major touristy stuff, but love the city and wouldn't mind doing it all again. Also, how is parking there? are there lots of garages?
