A coworker just told me about a website that gives you the walk score of your neighborhood. You put in your address and then get a score from 1-100 on how walkable your neighborhood is. It takes how far grocery stores, restaurants, stores and parks are in relation to your house into account to determine your score.
I got a 65 which is somewhat walkable. For San Antonio and Texas in general I was happy with that. I know you New Yorkers will beat us all but I thought we could compare.
