So I was in London on Saturday, and spent some requisite time wandering around Trafalgar Square in the rain. Like Times Square in NYC, Shibuya Crossing in Tokyo, or other such urban centers, Trafalgar square is alive with bustling activity, tourism, and, well, masses of diverse humanity. Moving around the throngs of people on Saturday reminded me of just how much I love being in international cities and particularly these sorts of iconic public spaces.
