I came across this really cool website that give you a score for how "walkable" an address is. It will give you a score 0-100 based on how close you are to grocery stores, bars, schools, restaurants, etc. Obviously its a little more applicable for Monkeys living in urban areas but a cool site none the less. The house I'm moving to next month got a score of 88
