Walking a retrospective....

Perpetual traffic guru Tom Vanderbilt has a series on the history and state of walking in America. It's funny that this came up since I periodically take the shuttle to work which involves a 10 minute walk to the shuttle stop and it felt so strange, but when I was recently in Tokyo and Seoul I walked a lot more for the same period of time and wondered to myself, "why does a 10 minute walk feel different in a city, suburb or the woods" City and trail walking feel refreshing, while walking in the suburbs feels alienating. Perhaps something to do with safeness.
