Is it sad that I'm impressed with myself for keeping this up for three whole days in a row?
I've visited London once for about six hours when I had a long layover at Heathrow on a trip to Italy in high school. Luckily, they let us out of the airport to do a bit of exploring. We managed to pack quite a bit of sight-seeing into one afternoon. One of the things I remember most is how interesting the pigeons looked, though. They just looked more beautiful than North American pigeons.
