National Geographic : 1958 Dec
A picket fence of frozen walleyes, noses down, stands in the snow of Mille Lacs, Minnesota. Ranging from a pound and a half to seven pounds. the fish represent one family's weekend catch. Minneapolis people at right camped in comfort in their 42-foot trailer. Driving onto the frozen lake, they heated their mobile home with a port able electric generator, dug holes in the ice, set their lines, and stood watch behind sealed win dows. When a bobber jumped, all rushed out to see what they had caught. Game warden's snowmobile took me skim ming up to 60 miles an hour over thin ice where no automobile dared to go. Jerry Liemandt, who checks fishermen for violations, patrols Lake Minnetonka, Minnesota. Propeller and 85-horsepower aircraft engine drive the skis. A built-in trailer hitch allows the warden to tow the snow sled from lake to lake. Here the wheels are retracted.
