I've seen it a few times. The last time was in January when I was in London for a protest. A friend and I decided to take a load of photo's of the tourist spots and of course some of us with big ben was top of the list. Going home on the train that day however I managed to delete all my photos of our day, I was totally gutted! Oops! Hopefully I'll be going back again sometime in the new year and this time I'll be letting someone else in charge of my camera!!
