First commute in a few days, it's been mild (and rainy and then icy afterwards) and unpleasant but today was nice enough with a dusting of fresh snow on the roads and paths. It was -12C/10F but with a windchill (during downhill runs) of about -23C/-9F that proved more than my tights and light shoes (that was a mistake!) could handle so my toes, knees and thighs were a bit cold when I arrived.

I normally leave my bike outside overnight at home which hasn't been a problem: yes, snow might fall on it (easily brushed off) but with temps in the -20C/-4F or lower, I wasn't concerned about freeze/thaw rust development. However, last Thursday, it went up to 7C/45F with a bit of rain and I forgot the bike was outside so when I brought it into the garage on the weekend, water must have gotten into the drive chain and frozen there because the rear derailleur wasn't shifting this morning (well, it would, about 200m/yd down the road after I had shifted on the handshifters). The bike is inside the indoor bike cage at work now so it will thaw and should be fine for the ride home.
