I spent a couple of days last week in London with my wife after working a convention in northern England.  Most of the time I was just trying to keep up with her so I didn't snap too many pictures.  Here are a couple from the Tower of London, St. Paul's, and the Parliament Building with "Big Ben."  I've titled this first picture "The Old and the New" which really captures the feel of modern-day London.
