Checked weather forecast, it said -11C. When I got there it was -32C. I didn't notice before the metal in the car started making popping sounds. Weird stuff starts happening at that temperature.
I've noticed that -32C is the temperature at which the engine oil in my generator freezes solid at my place up the bush. That's when I'm glad I switched to a Honda EU2000i. It's light enough to carry it inside and warm it with the woodstove until it will turn over.
That's why most people who live in the country use a block heater.
It also seems to be the temperature at which the trees start to make cracking noises. I wouldn't want to live in the tropics though. I like how fresh, clean and healthy everything is in the spring. 4 seasons rock.
