Would it be possible for you to ride all winter? I did it last year here in Saskatchewan and I plan on continuing it indefinitely. I spent the money and bought the gear (studded tires and clothing) and I always had a back up plan. The days that put my safety at risk I took the bus (below -30C or too much snow on the roads).

I sold my car earlier this year and I am quite content to see gas prices rise ($0.999/litre in Regina). It does affect me in terms of the trickle down effect on transportation etc. but I think as a society we need to come up with more efficient ways to live so we don't rely so heavily on fossil fuels.
