Huell finds out how oil made Kern County great, visiting the vast Midway-Sunset Field which is the top oil-producing field in the lower 48 states and the West Kern Oil Museum in Taft, which has one of the last huge wooden derricks in existence. Huell's last stop is the site of the Lakeview Gusher, which at the turn of the century was the largest gusher in the United States.
