I worked at Camp Bendleton, CA as a civilian programmer back in the late '60s, and one day Pres. Nixon was scheduled to show up. I think it was in the middle of the scandals, or it might have been when he ramped up our intervention in Vietnam.
Anyhow, we were in a taped off area behind the PX which looked down on a paved area. His limo drove up, Nixon stepped out and gave the above spread-eagled greeting. NOT ONE FREAKING SOUND of greeting came from over 100 Marines and some staff there. After a few seconds of dead silence, I felt embarrassed, for he WAS the President. I started to clap but just then he turned around and got back into the limo. That was when I got some idea at how pist the Marines were at him.
