pretty much it is awesome
My parents house here in Hudson near downtown gets a score of 63 "somewhat walkable" which is not bad for a suburb.
walkable neighborhoods are the future of development, in this geographer's opinion anyway.
anyhow, you should go there and type in your address and see how walkable your neighborhood is beacause it is fun and maybe you will see that you can easily walk or bike places and not have to drive all the time.
also this is a great interview about the US's obsession with bottled water.
