It's a good thing I didn't have farther to go today... Philadelphia is a lot hillier than I had anticipated, and getting into town was trickier.  I stopped at a bike shop in West Chester and got an official bike map of the Philadelphia area.  The proprietor gave it to me for free because he knew it to be inaccurate, and he gave me some tips about roads that are better or worse than indicated.
