Ice Fishing Huts on Lake Manitoba

People do this for pleasure. It is probably between -20 and -30c. We are on a frozen lake (Lake Manitoba) at Gimli. Hobby fishermen drill a hole in the ice (around three to four feet thick), usually with a petrol driven auger made for the purpose and sit in the cold with a toy-like (very) short fishing rod over the hole, which they have dragged their hut over. The hard core fishermen have a generator going outside to power a television (to watch ice hockey, of course) and a fridge which has the dual function of stopping the beer from freezing and providing some heat for the hut with its heat exchanger. As they fish the hole slowly freezes shut again. Outside, meanwhile, the ice makes pleasing cracking and moaning sounds.
