This is probably old news but I just found a website that give's your neighborhood a "walk score" out of 100. I love to walk places and its one of the things I love about DC is that I usually can. I was kind of bummed that I might have to give that up when we move (especially since we are a single car family and have no plans to change that). Well turns out where I live here has a score of 80, and where I'm moving has a score of 79! So basically the same!
Anyway, I think the website is fun and I'm occupying myself looking up every address I've ever lived at.
ETA: the website is walkscore.com
