Spot the difference

It's hard to spot the big difference between the photographs of these two "squares", taken just days apart in Union Square , New York and Berkley Square, London. If you are really, really observant, you'll see that everyone in the New York picture has either a balaclava or rediculously big hat on, and the people in the London picture are enjoying their lunchtime snacks in the sun. Hmmmm -- I'll take springtime in London!
