We went and saw the Changing of the Guard at Buckingham Palace. The surrounding areas were impressive, and it was fun to say we were there, but it wasn't necessarily a must on our trip. If you ever go to London, stop by Buckingham when it's not so crowded to take a picture of the grounds and the little red soldier dudes, but you don't have to stay at the actual change...just a tidbit of advice.
(Yes, Logan really did take this picture, this is really what it looks like. Amazing, yeah?)
