When I was working in Prudhoe Bay and would have to take the Cat out to do some pressure readings, I'd smoke in the cab and it would be -80 to -90 outside. I'd bundle my big ass up, run out and take the readings I needed, then get back in the cab and keep smoking my Flor de Olivas while I got warm. Great way to spend 10-18 hours every day.
Holy crap man! Where on god's green earth does it get that bitter cold? Yellowknife? I hope that's Fahrenheit...
