I one took a trip to Mongolia in the dead of winter one year. -45 C at night, -25 C in the daytime. I hate cold, but I wanted to see life in such an extreme environment. Very eye-opening, but I was glad I had my winter hiking gear and ice climbing socks with me just to walk around town. I can't imagine how it was for people thousands of years ago.<p>A few photos here:
