WalkScore is a site that rates towns and neighborhoods based on how easy it is to get around on foot - The way it works is essentially based on how close a place is to businesses. So in a way, the site is as much a measure of population density and zoning regulations as anything else.
When I think about the places I would want to live, it ultimately comes down to the single issue of how pedestrian-friendly the place is. Living in New York was great for this reason, and Lubbock, TX was terrible. As a kid, we lived across the street from a library, but the street was a 12-lane highway with no place to cross. We had to wait for my dad to come home with the car so that we could drive across the street.
Walking home a little drunk at 3am, stop in at Kennedy Fried Chicken.
At this hour in this neighborhood, guys behind counters always seem happy to see a whitey stop in.
"What's hot?"
"Hunh?"
"What's ready?"
"Wings!"
"Wings it is then. 6 pieces, please."
