Building Yellowstone Park with 1933 Chevrolet trucks

This is the final video in our series commemorating Chevrolet's 90 anniversary in Janesville, WI.
So far we've talked about cars, but Janesville made trucks, too. For example, 1933 trucks.
Twelve 1933 Chevrolet trucks were used by the Civilian Conservation Corps to build the roads and facilities at Yellowstone Park, this country's first national park..
You will see the trucks, but most of the vintage video is a beautiful 12 minute travelogue of Yellowstone.
