I really do love being a tourist in London. I love walking through the old squares, navigating the tube, and taking in the array of people and smells that permeate the streets. I even like London when it is freezing cold, which is a good thing really, because when we woke up on Sunday morning, it was snowing. Unfortunately the snow wasn’t sticking in the city, but there was a layer of sludgy ice on the floor and the temperatures were Baltic. Sunday was all about the Harry Potter Studio Tour in Watford to see Hogwarts in the Snow, and it really turned out to be a day that was affected by the snow: it tooketh and it gaveth in equal measures.
