Philadelphia has been called the fifth-most-walkable city in the country, and for good reason. But it's also the most strollable city, and the warren of historical streets in the Gayborhood, the cobblestones of Society Hill and the splendor of Delancey Street especially satisfy. We gathered just a few photographs of the streets we like best to get you ready for the weekend. Oh! And contribute to our Flickr Pool if you have shots of your favorite Philly walks. Enjoy your weekend!
