Unlike the DC area where a few inches of snow closes the schools, there's no such thing as a snow day in Steamboat. But we do close the schools when it gets to -40 (F or C take your pick because that's where the scales cross). At that point there's simply too much risk of kids getting frostbite waiting for the bus and unless we're planning to change our system of arithmetic to Base 9, I think it's a good idea for small children to keep all ten of their fingers.
Anyway I mention this because the Steamboat schools closed today due to weather for the first time in 22 years. Interestingly Marie and I were here in Steamboat on our honeymoon the last time this happened in February 1989. We were staying at a hotel that is about 500 yards down the street where we now live.
