If I'd had a car over the last few years, it would have been used on the crap wet days 27-45F. Crispy, dry snow is pretty nice to ride on/through. 2nd the wool. Dbl wool socks in big rubber boots and water resistant windproof pants, balaclava, goggles and flip-mitts down to 10F, and full snowboard mitts below 10. I'm usually plenty warm at mile 1 and sweating at 2.
