@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.
