Oooh, the colds this year want to hang on. I had one and it was almost 3 weeks before my nose was back to normal. Ack! We haven't had the flu hit the area--yet.

As for cold weather riding, I'm sure the TE'ers steered you toward wool.
I layered a silk long sleeve tee under my jersey and it really helps. Also, windproof stuff will provide a more comfortable ride.

Christmas morning I headed out for a ride with bike shorts and fleece lined tights, long sleeve jersey and windproof jacket, gloves, Polar buff around my neck and shoe covers. When I finished I learned it was 28 F!
