second bike commute day

very windy, and it's getting dark early. I'm going to need some kind of bike light, I think. I was worried that a single speed might be too painful for the job, but the gearing is just about perfect. According to the bike computer the whole commute is 8.9 km, which took 20 mins, so ~16.8 mph average. Not bad for a 20 year old steel frame bike with an alligator horn.
