Christchurch rarely gets more than a smattering of snow a couple of times a year, all melted again usually within 24 hours if not much sooner. Today it looks like it is a once in every 5? 10? year type snowfall and buses and many other city facilities have closed for the day. We have no equipment or experience to deal with 10 or 15cm of snow, though these might be quite normal - minor! - in some colder countries.

Even knowing it will probably add to city and business costs, after the violence. sludge and dust of so many earthquakes the snow feels extra peaceful, cleansing.
