I was there in 1965.
That spring my mother realized, to her horror, that she had never taken me to Wash DC, so we planned a vacation for that summer. Daddy could not get off work, so it was a big deal that mom and I went by ourselves on a vacation. We spent 2 days at the fair, a couple days around NYC, then to DC and on to Williamsburg and Monticello.
What I remember about the fair was walking, and the General Electric pavilion. Mom could not get me out of that pavilion.
Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has. Margaret Mead
