At least they have snow. Lots of it.

According to The New York Times, the people charged with making snow for the mountains around Sochi, Russia, got lucky with the weather in December and January.

There's a science to making good snow, and it has a lot to do with a deep understanding of temperatures and humidity. Rosa Khutor, the venue for the Alpine events, is just 25 miles from the Black Sea, which is subtropical and can make snow-making and course maintenance difficult.

When the skiing and snowboarding competitions kick off Friday, there should be plenty of the man-made stuff for quality competition.
