The Denver area is going through a warm up period. The commute in yesterday was good. Temps were in the low to mid 30's along the river and there was not any wind. I saw 2 other people on bikes. This is much fewer than what I see during the warmer months.
For the ride home, the temps were in the low 60's and the wind was at my back. The sun was shining and the ride was sweet. There were many more bikes out. I was able to help another biker out who needed a hex wrench to tighten his bottom bracket bolt.
I was getting concerned about finding a weather window that would allow me to commute at least once in January. As it turns out, it looks like I will ride again tommorrow.
