Nah...living in western Wyoming at 7000 feet and working at 10000+ feet during the winter....THAT'S cold. it got so cold that the equipment had to be left running 24 hours per day or the diesel #1 fuel would gel...the hydraulic and gear oils would get so thick they wouldn't flow.
Everyone had dipstick heaters, block heaters, stick-on heaters for transmissions and differentials, and even battery heaters. While the official record cold for Big Piney is listed at -37F, locals know it gets colder than that. In 1985/86, the water mains froze. We were without water for about 4 days till the city got them thawed out.
Growing up in Spokane, temps regularly dropped to -20 or more in the winter...
My first winter in Kahleeforneeya, I was working on a construction project at one of the local prisons. All the crew was wearing heavy Carhartt work clothes, stocking caps, gloves, etc...and complaining about the cold. me, (having just spent a couple winters in Wyoming, wore a flannel shirt and a light jacket...and called them a bunch of pussies...
Fast forward a couple of years...I started wearing the Carhartts, gloves, and stocking cap...and complaining about the cold... I had become acclimated to the mild weather...in short, I had become Californicated...
