Trust me, there's a big difference between 30F and -30F.

I have a pair of boots I don't even think about putting on until it's -20F or colder. (and I've worn them for weeks on end at the sunny fun spot called FT Drum)

Sunburn? That's a severe hazard in ture cold conditions as well.

In the meatime, I'll have a coffee or 10 and a seat by the fire to warm up the tootsies!
