We went to the World's Fair that year, but not to SDC. I bought a Chinese doll at the fair, and I remember the Japan exhibit had fountains in front of it. It seems like we saw a miniature circus. The American pavilion had a motion simulation film.
When you mentioned the fair, I had some memories pop into my mind. I don't seem to remember to much--lol. I was six, I believe. Sorry to divert the thread a little.
