You know when it's cold because the Geordies go out on the town with 2 t-shirts on
Do you need a block heater at those temps?
Ya, I've heard of people getting frost bite on you know who because it wasn't completely dry.
The cold is different over here though. It is dry. Yesterday it was -20 odd and although it was cold because of the wind chill it wasn't "that" bad.

Snow is 10x better!
