One of the speakers at the weekend was a young South African guy who had spent two summers and a winter at their Antarctic base (deep under snow/ice.) One of their diversions was to hold a "streak" outside. This involved running naked some 100 meters around a building outside before plunging back down the ladeder and thawing out over a heater! He showed the course but excused himdelf for not showing the participants. "Anyway, at that temperature, there's nothing very impressive to see!", sez he!
