We rode. 43 miles, starting temp about 20ºF, finishing temp 28ºF, wicked NW wind blowing a steady 20 mph. It was gnarly, but as all rides with unGodly wind-chill temps, not nearly so bad after the first 10 minutes and much more tolerable riding with a friend over to a fast competitive group ride. A ride of that description is considerably harsher when you're grinding into the friggin Maw of Winter alone @ 15mph for three hours.
