A visit to the Rockford snow sculpting competition.
That year, as this year, early January was too warm for the competition, but toward the end of the month the organizers were able to get the event in. Techniques for manufacturing blocks of snow and keeping them from melting have improved; ten years ago the source of blocks was snow scooped off runways at the airport.
Some years, the contest date has to be changed account cold weather, either because the crystallized snow is too brittle to work, or because there's a risk to the sculptors.
