I started taking my bike to work last spring because once again they raised the taxes on cigarettes, so to make my budget work I cut out public transportation. I have lost weight and havent felt this good since I was in high school (not that long ago I am 25), so far this year the smokes have been pretty good to me, or perhaps its the taxes. I ride a 96/97? Gary Fisher Tassajara and am looking forward to a new Cannondale R600 sometime this January because it is just too hard to keep up with the roadies on the Fisher and I do not like being passed.
So far I love winter commuting here in Chicago its a nice kick in the pants in the morning. I usually ride the bike path by the Lake to Michigan Ave. but I found out the lake does not always respect the artificial boundries imposed on it and reacts in cooperation with the temperature by coating the path in places with glare ice. So I took a couple of tumbles and found a new route.
One last thing, I have always loved the winter, in the past though I have mostly experienced it one step removed, usually through glass of some sort (windshield, bus window, or TV screen). Now however I am in it for at least one hour a day (in Chicago we measure distance in time) and I love it, I feel like a wild animal. It is better and not much harder than summer commuting. All you have to do is not stop, adjust in small incraments one day at a time and before you know it its 15F with 5inches of snow and you cant wait to get out in it. One thing I find helpful for the cabs that get to close is steel toe shoes, tap their sheet metal and they realize you are there, also suprisingly warm, cheers
