I actually went to that event as a high school trip.
I think I have a photo of me sitting on one of those benches.
I was there in 1964.
Funny story...Dad offered my sister and I GE “portable” B&W TVs for our bedrooms in exchange for NOT going to the World’s Fair in NYC. We took the TVs. I still regret that. I think Dad got them at the GE company store for cheap, too!
We drove from upstate NY to Westchester, NY to see his folks a couple times a year and then over to Stamford, CT to see his sister and family. Those were good Thanksgiving and Easter trips, but I don’t think Dad liked the idea of yet another trip to NYC in the summer.
