#9 - It'll snow the day after you take off your studs.
Seriously, I just got my new summer slicks yesterday and mounted 'em right after class. There was a bit of snow coming down last night but none of it was sticking, figured it'd be slop by this morning. Woke up this morning to solid black ice under half an inch of snow. It's been 40*-45*F every morning for the past two weeks, and I've been rolling studs on wet pavement the entire time waiting for my new tires.
I hate riding the bus.
