Exhausted in London

Nate didn't sleep at all. I slept for about 2 hours total. But we're in London!  Trying to push through fatigue (on our 3rd cup of coffee for the day). 

Met some very nice Americans who live in Cambridge at breakfast who gave us some wonderful suggestions. 

Went to the National Portrait Gallery, Trafalgar Square, and St Martin's in the Field all before noon.
