Frozen nose hairs. That ranks way up there as one of the oddest sensations. -15° will freeze those hairs for ya, if ya wanna try it. I have places to be and things to do, so I'm off already. Well, after the weather of course. -15°, 77% humidity, calm winds (thank goodness), and fair skies. And at least another 5 days of this sub zero weather.
Stay warm, Travelers. The body needs it.
