FWIW, my current address [[in Detroit) rates a 92, my most recent former address [[also in Detroit) got an 85, the address where I grew up [[in an inner-ring Detroit suburb) is a 52, and another former address of mine [[in a very nice, very functional city very far away from here) got a 63. I don't know if that says more about my past and present neighborhoods or Walkscore's methodology, but there it is.
