In the Denver area today was significant for a few reasons.
First, it was the first full day of winter. Winter commuting season is THE season. If you commute through winter by bike here you are hardcore.
Second, today there was about a foot of snow on the ground all over the Front Range and the metro area. Some places, like Coal Creek Canyon and parts of Boulder County, had almost three feet of snow. In my estimation today was an unrideable day, but I have a feeling there were people who rode. For me, having a ten mile commute, I just could not rationalize getting out on two wheels. The roads I normally travel were not conducive to cycling. And with the snow coming down as steadily as it was, no amount of clearing would have made the paths easy going.
And third, today marked winter solstice. While winter will be settling in over the land and pummeling die-hard cyclists, the days will only be getting longer, lending more light by with to see the sheets of ice and snow drifts, and to melt the lingering snow.
I'll be driving again tomorrow. My opportunities to drive (ugh, did I just write that?) are so few that when they coincide with a major weather event I feel compelled to take advantage of them.
Oh, and there's only two more shopping days until Christmas...
