Goddamnit, PAT, it's hardly a mystery. The class schedules are published. Maybe you want to make changes in your own schedule? I'm just saying.
I'd biked most of the time, but I am too much of a wimp to do so in the snow and such. And my rear rim got bent again, so it's not like I could just take it out during the nicer days. (I suspect the cold helped generate that issue).
