We are currently watching a PBS 6 part series called The National Parks - America's Best Idea. http://www.pbs.org/nationalparks/ They are breathtaking and I have to say the scenery leaves Scotland's majesty in the dust !!!!!!
Any hoo the brain and and one of the driving forces behind the creation of the parks was a Scotsman, John Muir, who hailed from Dunbar, East Lothian. His parents moved the family to Wisconsin in 1849. An accident in 1867 became the catalyst for what was to become a life long worship, and dedication to the preservation of nature. He greatly influenced President Roosevelt in his conservation pursuits.
We all owe this Scotsman a great debt for his dedication to help preserve such wonderful natural beauties - Yosemite, Sequoia, Grand Canyon, Mount Rainier and other areas like The Petrified Forest.
