The girl who was the valedictorian of our high school class was Japanese, and she went to work at the US building at the Osaka World’s Fair in 1970.
I’m yet another one who went to Expo ‘67 in Montreal when I was very young.

And me.
Me too, but I was born in 1961, so I … almost have a memory of it! I sort of think I have one faded mental image of a low building making a very loud noise, but that could be one of those ghost memories from being told about it. It scared me and I cried.
Hemisfair '68, in San Antonio. I was 10, and saw my first bare breast, first street beggar, and went on my first plane ride (Lockheed Electra). It was a memorable trip.
1964 New York on a weekend free from the US Navy Class A Yeoman class I was attending at Naval Training Center Bainbridge, Maryland. I didn’t see Michaelangelo’s Pieta statue there but saw it in 1965 at St. Peter’s Basilica 1965 when my Sixth Fleet flagship made a port visit to Naples. I remember seeing the year-old touchtone phones at the fair.
I went to the '64 NY fair. One of my memories of it that I would tell people for years was apparently a false one. We rode on the monorail and I remember standing in the nose and honking the horn. More recent research has me doubting they even had a horn. I was really unappreciative of the whole fair experience: from the monorail I could see over the fence where a regular carnival midway was set up, and i was rathering I was there.
Went to New York, '64 and Montreal '67. Which was the one that introduced Belgian waffles to America?
In New York, there was plenty to see and do, but what did me and my brother like most of all? A cheesy little sideshow that was based on Sea Hunt - there was a big tank of water and a recording of Lloyd Bridges, narrating Mike Nelson-style, a story about a sea monster, which was supposed to be serious but the divers in the tank played it for laughs - the monster wore these long socks, which he had to keep pulling up. We went to that one twice.
Belgian waffles were served at Century 21 (Seattle 1962). Don’t know if that qualifies as introducing them to America, but they were considered quite exotic.
I was living in the Spokane area in 1974 and went to Expo '74 once. In general, very underwhelming. The IMAX theatre in the US Pavillion was impressive (it was a new technology then) but the best of the expo was the German exhibit. That’s only because they had a beer garden. I was only 20 but they didn’t card me and I probably had one or two too many. Hey that German beer was great compared to the usual American beers of the times.
I went to the NY World’s Fair three times in 1964 and 1965, and went to Expo 67 as well.
Loved the World’s Fair in NYC. They renamed the Flushing Meadows subways the Subway Specials to the World’s Fair. The Unisphere. The many Disney tie-ins (They did the GE Carousel of Progress, the time travelling Ford cars in the Ford exhibit (with audioanimatronic dinosaurs!), the audioanimatronic Abe Lincoln at the Illinois pavilion (which they later expanded into the Hall of Presidents at Disneyland). And, of course, the It’s a Small World After All show at the Pepsi pavilion. (They did a great job of reconstructing the way that looked originally in the movie Tomorrowland ( https://www.youtube.com/watch?v=hU5iQ3n9GHU )
My sister danced (with the rest of her dance class) in the New Jersey pavilion. We saw the Pieta at the Vatican pavilion. The Mormon pavilion had a replica of the Salt Lake temple. They still had the New York City pavilion around from the 1939 World’s Fair. The IBM pavilion featured “The People Wall” and its giant egg shape by the Eames brothers. The Chrysler Pavilion featured sayings from “Carfucius” and a model of the Turbine Car (I won a model of this). Sinclair had its DinoLand, as at the 1939 Fair a quarter of a century earlier.
Great stuff. It lost money, like its 1939 predecessor, but unlike the 1933 Chicago Century of Progress fair. And it was considered “too commercial” to be a proper World’s Fair.
Expo '67 was completely different. Not as much commercial stuff, much more international exhibition. No Disney, aside from the clip of Snow White and the Seven Dwarfs playing in the US Pavilion (a Buckminster Fuller geodesic dome) And it was held in Montreal. My parents, astonishingly, let my sister and myself go off our separate ways. In a foreign country, where the main language wasn’t English. It was a different time. I loved the British pavilion and the giant Kaleidoscope and the Canadian exhibits on Science and the Human Body.
The next one was in Japan – Expo '70 – but there was no way we were going there.
My parents took me and my sister to the New York World’s Fair in the summer of '64. I was just shy of my seventh birthday and my sister had just turned five. We checked into a real hotel (it had an elevator!) with adjoining rooms and my Dad had to pay to park the car in a multi-story garage(big city #%*@!). At the time I thought we stayed at a Waldorf Astoria rival, but since have come to realize that it was a rathole 
The things I remember most:
‘The World of the Future’ with displays of kitchen appliances that all folded out of walls, and a self-driving car that followed a track around the pavilion. I got to “drive” the car and the driver’s seat swiveled around so I could play a game of chess with my Dad who was in the back seat.
The Pieta
The animatronic(?) dinosaurs and the Sinclair brontosaurus that was made right before my eyes by injecting molten plastic into a mold. I think my name was engraved into the bottom of the dinosaur, but I’m not sure. The beds in our hotel rooms had metal shades on reading lamps that were attached to the headboards. On the night of my Sinclair dino acquisition I placed it on top of the reading lamp and fell asleep while reading (probably a Roy Chapman Andrews book - I was nuts about dinosaurs). When my Mom came to check on us later the dino had melted all over the reading lamp and was smoking slightly. I don’t remember if my Dad had to pay the hotel for scraping a plastic dinosaur off the reading lamp
The only World’s Fair souvenir I now have is a carved seashell from the 1933 Chicago World’s Fair that belonged to my grandmother.
Belgian waffles! Yes! After seeing them at the World’s Fair, I have spent the rest of my life seeking them out and immersing myself in their heavenly, delicious beauty!
I had forgotten all about seeing and eating Belgian waffles for the very first time!
Now I want one…
Solvang has these gustatory delights.

If I had thought of this thread a few years earlier, we could have organized a 50th anniversary party. 
Which also got reused at Disneyland. If you took the train around the park, you’d go past an exhibit of the Ford dinosaurs.
1974 World’s Fair, Spokane. It’s my home town even though my family wasn’t living there at the time. I was 9 and got really pissed off at being denied riding the roller coaster because I was too short.
Between the Tomorrowland and Main Street stations, as I said in post #23
I went to the NYC fair at the age of 7. I remember “Its a Small World” ride pretty clearly, a tire-shaped ferris wheel (UniRoyal), the Unisphere and some attraction where the stage rotated showing the evolution of technology or something. Maybe General Electric?

New York City in 1965 (although I was too young to remember it), Montreal in 1967, and Knoxville in 1982.
