On a Run For The Wall trip that meets up with the annual Rolling Thunder in DC, some of us made a side trip to Window Rock (Navajo Capitol) by their invitation. They lined the main street with US Flags and cheered us on. Yes, I got choked up as well as the hard-core VN combat vet/bikers. If that wasn't great enough, they had a big festival planned on the Capitol grounds, with food, beverages, live music, award ceremonies, and even Color Guard parade.
I can't think more highly of the Navajo Nation. They are true American patriots. Then there were the Marine Code-Talkers in WWII that were key to many major battles that defeated the Japanese.
