Imagine having a camp in below zero weather, exposed to the elements and unable to see the thing you're trying to catch. On Lake Mille Lacs in Northern Minnesota, thousands of anglers drag their fully-equipped, four ton houses onto the lake. Resting on two-foot thick ice are generator powered homes, costing 20,000 dollars, complete with microwaves, surround-sound, satellite hook-ups and underwater cameras to locate the fish. The fishing holes are drilled indoors through carpeted, parquet floors. Years ago, there was no way of knowing where to drop your house to get the fish. Now a computer spots the reefs where fish are feeding; beneath the ice. Factor in a global positioning satellite and you've found the perfect spot.
