When we went skiing today at Bridger Bowl, many people were complaining that it was cold. I think it was in the low twenties; I hardly noticed. As of 5:00 p.m. this afternoon, the snow report said it was 20 at the base and 15 mid-mountain. Since the slopes are east-facing, I would imagine that the temperature dropped quite a bit as the sun sank over the mountains.
My gosh! Temperatures in the 20s at Spirit Mountain in Duluth would be a warm winter day.
