What's the coldest weather you've ever been exposed to?

So I'm curious as to what is the coldest weather you guys and gals have been exposed to? Living in Alaska, I've been exposed to some pretty cold weather during the winter. However, nothing can beat the -80 with wind-chill from this past January. We had a couple of weeks where it was very very cold and windy. It did a lot of damage to buildings and houses. We had hurricane force winds too which caused a lot of vehicles and signs and other structures to be blown over or damaged
Here's some pics of that that I braved one day to take.
