Wherever you want to live, Walk Score lets you know what's within legs' reach. My place scored only 62 out of 100, in contrast to a benchmark downtown Capitol Way address's 92. Still, above average, walking-wise.
Recommended by PZ, who also points out that sharks don't have legs. As Demetri Martin might say, "I'm afraid of sharks, but only in a water situation."
Oh, and thanks, Josh, for letting me borrow your Demetri Martin CD.
