Rick, thanks for sharing this wonderful trek. Although I am not an American, the history lessons, background of people, names, and places I have known through school and the news have now greater background, and may say, romance to them.
Also I found interesting the famous legacy of the Duvall family. Currently Robert is married to the granddaughter of Argentinian aviator pioneer Susana Ferrari Billinghurst. There must be something in this gene pool that keeps the family reaching some heights of success.
