I walked 18,041 steps today, or so the "health"/fit-bit app on my iPhone says. It's London. There is a lot of ground to cover, and we've covered a bare fraction of it. The Changing of the Guard at Buckingham Palace. Harrods Department Store. Interesting streets. People-watching. Lots more to see tomorrow and Tuesday, and, even though it's not my first time in London, none of it loses appeal. It could be a great city to live in if a person could afford to do it right. We don't get those choices.
