There’s a wicked cold snap across Northern New England these days, with -22F predicted for tonight. All the same, the Dartmouth College Winter Carnival is well under way, and this year the venerable ice sculpture contest is making a comeback. These two guys were among the many students working on spectacular works of art outside Collis Common Grounds near the Green in Hanover, in spite of the cold. The final results will be around for all to admire over the next few days.
