Jack London, in one of his short stories, (To Build a Fire?) spoke about the cold in the yukon -- and spoke of informal thermometers, such as it being cold enough for a wad of spite to freeze into a ball before it hit the ground, or of urine freezing before it hit the ground.. maybe this belongs in the "how cold is it thread"..

and Mc Phee (First name?) a writer for The NYer, wrote about the cold of his childhood, and how once his diapered brother was frozen to the floor when he wet himself.
