Peakster,
Props to you for becoming a year-round bicycle commuter in Winnipeg. I'm a bit of a wimp and only commute spring/summer/fall.
Here's a few more online resources for bicycle commuting:
MTBR.com Commuting Forum
and I don't know if you saw this on the Ken Kifer website -
Bike Commuting and Transportation
Also, I think that
The Immortal Class: Bike Messengers and the Cult of Human Power is one of the more entertaining / thought provoking books on cycling and modern car culture.
FWIW,
Tim
