It's been a really long time since that happened. Like late seventies long. I guess the last time was during the Great Blizzard of 1978 or as I affectionately call it, the Cleveland Superbomb.

Now, since U of M has declared tomorrow a shit show, I recommend staying inside. Maybe call a friend on your cup phone or play Wii Superbomb Sledding. It's really not a day to show off by braving the cold.
