Where'd all the degrees go?

It's mighty cold here in the Rockies. We've got all of 1 degree at the moment and never had much more than 7 at the highest today. Despite the cold, the conditions were actually quite nice for running this morning - there were a couple of inches of new snow on the ground which, because it was so dry and crisp, offered an excellent grip while running over previously snowpacked/icey surfaces. Due to a busy schedule, I only managed about 90 minutes of running today but have 3 hours planned for tomorrow. The forecast is for another dusting of snow (1-4 inches) and something between -2 and 0 degrees while I'm running. It's rather entertaining to see just where icicles form on one's body whilst out in this arctic air!
