The only time I had been in London (I think it was in the spring of 06) we didn’t bring any camera and the mobile phone I had at that time didn’t have a camera either, so we bought a disposable one that took some really … horrible pictures!. I had to throw them away because in most of them you hardly could tell that was London :). Anyway I kept a couple of them like this one where you can see the London Eye .. kind of.
