I went for a 25 mile ride on a different route than normal, upper 20's, 7 mph wind, all fixed gear. My riding partner had a balaclava and i had a headband/earwarmer on. As I was riding back, i thought that his face must have been warm, but how does he blow his nose? It must have been a pain, but it was just a thought of mine.

I just pull down the part of the balaclava that covers my nose, and blast, double barrel style. Works pretty good. I must expell a half cup of snot per day that way. Who says bikes are emissions free??
