I think I live pretty close to MileHighMark (just across 36, not far from Albertson's). I left home at 7:45, temp just below freezing. L/S wool shirt, poly t-neck, wool sweater each layer fairly lightweight. Fiddled with new ear warmers banging into my helmet even though it wasn't really cold enough to need them. I'm going about 9 miles each way.

I'll ride to a lunchtime appointment (about 10 miles total there) and home this evening.

First time I've done the winter solstice commute!
