re: What’s the coldest weather you’ve been in?

50 below in the Sawtooth Mountains in Idaho. Way up in the mountains. Zero wind. Dead calm.

Tried to start a Caterpillar that had a pony motor starter - very old Cat. Had about a 1-inch by 1 foot rope pulley/flywheel. I tried to tap the ice off the big pulley with a hammer. Didn't hit it hard. Just tapped it. The cast iron pulley shattered like it was made of glass.
