After my morning stroll, I visited a small fair at a local church just to see what it was like. It wasn't much to see, but it was fun to walk around and they had some live music.
In the afternoon I visited a bunch of tourist sites. I started by walking to the Wellington Arch and then wandering across to Buckingham Palace:
After that I wandered through St. James Park to Parliament, where Big Ben is located.
Then onward to Westminster Abbey.
A word to the wise: don't decide to walk to the tourist attractions if you live far away from them, especially when you have already walked a lot earlier in the day. After returning for the evening, I calculated the approximate distance I walked today, and it was over 10 miles...probably closer to 15.
