If there is a way to determine a definite level of awesomeness, "Walked on the Moon" would probably be a good start. Twelve men have had the honor of going where (few) men had gone before -- and all of them have been American.
So where are they now? Some have passed away, some are still with us, some have found God and others have found found art, but all have a place in the American imagination.
Moon Men, we salute you.
