Left at 5:45 AM at 18*F with a 15 mph cross/tailwind for my 14 mile commute. Face and eyes were fine with no fogging of eyeglasses or goggles; hands fine with only cold, but tolerable thumbs starting at mile 12. The feet started to feel cold at mile 7 but were tolerable to the end, though near the end I could tell they would soon get really cold.

The notable thing about this commute though was that I left my heavy duty Neoprene booties with holes for the cleats at work last night. I didn't want to take a chance riding without a shoe covering so I improvised and rode my mountain bike with platform pedals and strapless toeclips. However I couldn't find my other pair of Neoprene booties with the closed sole. As I usually do with the mtb for cold wet rides, I wore thick and thin woolen socks, leather running shoes and Totes rubber overshoes. For this additionally cold morning I added a plastic newspaper bag over my socks, and one over the shoes, beneath the Totes. This arrangement seemed to work as well as the Neoprene booties for these conditions.
