Two Armstrong stories.
Bob Hope brought him to Vietnam. We didn't quite know who he was when they showed up on Christmas day in 1969.
I was in one of the front rows. I was struck by how nervous Armstrong was; twisting his baseball type hat into knots. Hope made his jokes, of course, but to no avail in getting Armstrong to loosen up. He was a surprisingly shy man.
A few years later I hitch hiked for a couple years though Africa. In remote areas - remote areas - people would say "Armstrong! Man on the moon! Is he a member of your tribe?"
