In reply to Talius Brute:
Not done that, but I did go down one day a few years ago to work when practically nobody else did because of the snow. Many of the trains were off, buses were off and hardly any of the Tube was running. My train was fine, not even late, and it was only after arrival that I found out London was under about 8 inches of snow.
It was a brilliant day, surreal but really enjoyable.
