In 1968, I was 18 years old so I was sort of, kind of an adult. So the picture below really gave me pause. Everything about it looks so ancient -- like how you'd look at a picture of the Roaring 20s! Yikes. I guess I forget (sometimes) the technological changes that have taken place. I wonder where all those old switchboards are!
BTW, as you can probably tell, this is a Tweet from the LBJ Library.
