Nah, it keeps the riff-raff out. --- The ND Tourism Board
UND had a something-like 60-year stretch without cancelling classes due to weather. That ended in the late 1980s (early 1990s?). I believe the numbers "cfm567b27" put out were close but I also believe the wind gusts put the wind chill into the minus three-digits category.
That day was, to my mind at least, refreshingly crisp.
