Cooler this morning, dressed a bit better but not quite enough as I had to stop within about 10 minutes (of riding into a cold headwind) to add a balaclava to the skull cap under my bike helmet. The air temp was -18C/0F but with wind chill was about -29C/-20F. After a few more minutes, I realized that I should have worn my ski helmet instead, it would have been more comfortable and just as warm (as I became, after adding the extra layer, the balaclava).

I toyed with the idea of riding on the 1km/0.6mi skating track that's been made on the lake right beside where part of my route is but I decided not. Maybe another day. I do have studded tires so that wouldn't be an issue and furthermore, at 7am, in the dark, there likely wouldn't be any skaters.
