A little snow is no reason to tremble where I live. In fact the economy is helped by a good ski season. But in the U.K. a little snow, like that pictured below, causes much of normal activity to grind to a halt. They are not set up to deal with below freezing temperatures. The train signals may fail. So on the trip when I took this photo, near Rochester, England in late December we made just a quick visit to the Cathedral & headed right back to the train station to make it back to London where we were staying.
