So I'm off and running. I've got about 6 hours in London so I decided to get out. I took the Heathrow Express to Paddington. On the train I talked to someone who was coming home from a trip to San Francisco. She suggested that I take the Bakerloo line to Piccadilly Circus and have a look around.
The escalator in the underground was so steep that I nearly fell!
I just started walking around and I came down a small alley where they were setting up some fruit stands etc. I thought that this was a cool looking building.
