-19F on my way into work this morning. At least the wind died down a little from yesterday. Amazing phenomenon, one that I remember from childhood. Cold enough the last couple days that when you're outside, and spit onto pavement or snow, the spit balls up and rolls by the time it hits anything, like Jello. That means it's cold.
Although, in the mid 1950s, my dad was in the Navy, and spent 3 winter months at a weather station at Point Barrow. We would bitch about the cold as kids, and he'd say, "No, it's not cold outside".
