300 Club - Wikipedia, the free encyclopedia - http://en.wikipedia.org/wiki...
"Participants in the 300 Club wait for a day when the temperature drops to −100°F (-73°C) for more than a few minutes, generally in the winter. The persons first warm up in a sauna heated to 200°F (93°C) for as long as 10 minutes. Then they run naked in the snow to the Ceremonial Pole itself in the −100-degree weather, and run around the Pole. After this, they usually warm themselves back in the sauna again, often with the aid of alcoholic drinks." - JoeCamel
