I took a whirlwind trip to London for work this week and managed to carve out a few hours to see sights. The express train took me from Heathrow to Paddington, where I grabbed lunch and started my walk to Buckingham Palace through Hyde Park and the Wellington Arch. After a quick look I proceeded on to Westminster Abby and Trafalgar Square before catching the tube to Waterloo and a train out to Bracknell.
This shaky cellphone video is the only footage I have of the adventure.
