Walk Score

Walk Score is an interesting site to determine how walkable a particular location is. It's especially useful for house hunting.

While I'm a bit suburban by nature -- and certainly to get the highest scores, you'd need to be in a completely urban area -- but I also really do like having a number of places near by to walk to, and so this gives a good gauge of that.

(I've got about a 60 for a score -- and certainly I'm happy with what I have that is within a walking distance.)
