I saw it live. I was 17.
I had been working as a boxboy at the Shopping Bag supermarket in Sylmar Ca. when Kennedy was shot. The busy supermaket full of people came to a standstill when the radio broadcast was piped over the PA system. My shift ended within an hour. I walked home and my mother had the TV on. Really couldn't comprehend what the hell was going on. Stayed glued to the TV for days. Remember no commercials for a few days?
The Ruby incident was so bizarre.
It had only been a few months after the Cuban missile crises and I still remember the panic of panic grocery buying at my job that night.
