Great topic!

Boston was a fun challenge this year - I rode the bus only a few days during the heaviest snowfall period, and had fun optimizing my gear to the conditions. There is not a lot of difference between winter commuting and back country skiing in terms of layering and warmth, so the cold and wind were a non-issue for me. My ride setup with an 8 speed IGH and carbon belt would have been perfect if my fenders could accommodate fatter studded tires for the snow (35mm vs. the 28mm that actually fit); I'll have to decide next year whether to replace those beautiful fenders with something more practical or not.
