Interesting page here, only -65.2C at the moment though. [hehe]
Coldest Place on Earth?
The coldest I've been in was -50*C in February 1996 right at home. There was no wind though. In that temperature, fuel lines freeze, the air in your tires compresses, flattening the tire a bit,w hich then freezes into place until you get a few miles down the road.... and boiling water freezes before it hits the ground if you throw it in the air.
Frostbite also sets in within a few minutes to exposed skin at that temperature. It's dangerous stuff.
