I always forget that London has giant skyscrapers since they're all pretty much concentrated in one place. I stepped out of Canary Wharf station thinking I was in Gotham or something. Turned out I wasn't the only one thinking this as a German tourist walked past and said "which one's the Wayne tower?" to his friend.
It was a huge contrast to Greenwich where I spent the day doing what I do best - wandering around aimlessly. It's a really pretty place and you kind of forget you're in London, until you walk up the hill in the park and see the skyscrapers in the background. I just wish there had been clear skies today, it looks like someone rubbed out the top of the buildings.
