-20C with a 10km/h headwind this morning, so it was back to the goggles and respirator. Yet tomorrow will be above freezing again. I took the mountain bike today since I had moved the lights over to it before I got around to fixing the spoke on my touring bike. I think I'll stay on the mountain bike until we get another snow. It handles the bumpy, rutted ice a lot better. The one tricky underpass got plowed, so I don't have to get off the bike now.

I am getting very annoyed with my Light and Motion Stella headlight. It has a pathetically short runtime in cold weather, not even enough time for a round trip. And on several occasions including yesterday it has refused to charge. I plugged it in yesterday morning and the charger went to solid red to indicate it was charging. Last night the light was green indicating it was finished. But within 30 seconds of turning it on this morning it started flashing to indicate the power was low, and it died completely within 20 minutes.
