@giujohn,
Imet him once and had him sign a menu from an environmentl engineering meeting in the ground water center in Columbus many years ago. It was maybe 3 years after he was elected to Congress and was doing a meet and greet in tech centers in southern Ohio . He was very gracious when he talked with my group of students and was telling us jokes about hanging around with geologists in the program.
He was very very gracious, he never made himself the center of attention, when he easily could have.
God speed John Glenn.
