Wyoming – Back in 1932, John D. Rockefeller Jr. purchased the JY Ranch. It was Jackson's Hole first dude ranch, a place where tourists paid to experience a working cattle ranch. Rockefeller bought the land and another 32,000 acres in order to set it aside for an expansion of Grand Teton National Park. While he donated most of the land to the park, he kept the JY as a family retreat. His son, Laurance, decided to turn it into a nature preserve and give the land to the park, which finally happened last year. Rebecca Huntington reports.
