Okay, I think you can post this under: "WTF?!"
I was watching a Documentary about the South Pole. And one of the things that they do to amuse themselves, and earn a really cool looking patch! - is this little stunt.
When the temperature is 100 degrees below zero (Fahrenheit) the person going for the patch, must sit in a Sauna that is at 200 degrees F for ten minutes. Then wearing only boots, walk from the Building to the pole in the picture, walk around it once, and head back in. So 300 degrees temperature change, hence the "300 Club".
When they do the walk, with only boots on, they can't go too fast, or they breathe in air that will freeze their lungs. They can't go too slow, or they will get frostbite. People are standing by to help in either case. But if you make it..and circle the Pole (which I think is a very clever physical pun!) you get treated to Whiskey and Cinnamon Roles. Plus you get that really cool patch. A patch I have never seen on anyone. But I do have a friend who spent the Winter down there when she was in the Navy...and I shall ask her about it. In Winter, there are only about 40 or so people down there to keep it running. To get a cold beer she says is very easy:
"Kevin, you just open a window, put the can in a pair of tongs, stick it out, bring it right back in..and there you go. Cold beer. "
And I did not realize, until I met her...that the entire continent is at 9.300 feet above sea level. Almost twice as high as Denver. And it is a desert too! So nose bleeds are common from the extremely dry air, and humidifiers go full blast.
I think I will never earn that badge.
