Consecutive bicycle work commute number 1554:

For some reason it seemed extra dark this morning. I'm not sure why. I mean, any morning before the sun comes up should be as dark as any other morning, right? I'm guessing it's just a perception thing.

14°F with a very light wind. 90% of the pavement is now clear, but there's still some stretches of rutted ice so I'm still on the winter bike with studded tires.

Was about 1/4 mile from home when I thought, "Something feels funny." Reached up to feel nothing on my head but the neoprene of my balaclava and realized I'd forgotten to put my helmet on. So I turned around and rode home to get it. Despite the extra 1/2 mile of riding I still made it to work four minutes faster than I did yesterday. I have no good explanation for this, as it didn't feel like I was riding any quicker than usual.
