Woohoo! -23 degrees, windchill -32, and I experienced it first hand. It was really cool...(get it?) During the walk from home to school, I have this small area on both sides of the cheek that is the only part of the entire body that is exposed to air. Well, by the time, I arrived inside, those small areas are basically frozen. There is an interesting feeling to it, actually... Anyway, that's the fun for the day. Oh, and I need warmer pants..........
