National parks and Rockefeller

I was basically transfixed in front of TV in the last two nights to watch PBS "National Parks" series. In addition to the breathtaking scenery and early Americans' vision to preserve the pristine beauty, I was impressed by the philanthropic mind of the oil mogul, John Rockefeller Jr., son of the John Rockefeller Sr. He donated US $45M (probably worth US $500M now) to the land purchase and other activities for the national parks of Acadia, Grand Teton, Yosemite, Great Smoky Mountain and others. Some people use their wealth to flaunt their own pride while others use their wealth to show and preserve the national pride.
