Philadelphia Walkshed

Walkshed lets you see how walkable any Philly hood is: just plug in your address and tell it a bit about what you're looking for, and it'll provide color-coded, 1 (least walkable) to 100 ratings (all accounting for highways, rivers, and other barriers) for stuff like notable bars, restos, grocery stores, bus stops, and even PhillyCarShare PODs, where you can pick up your ride, from which to laugh at people actually walking places.
