Wow. At 59 I try (and usually succeed) in avoiding the loathsome impulse to be nostalgic, but it was tough while watching this home movie because my dad and I went to Expo 67 in the summer of (what else?) '67. I was not quite 12. I remember visiting the U.S. pavilion designed by Buckminster Fuller, remember riding in the hovercraft your grandfather caught once or twice on film speeding over the water, remember visiting the Kodak pavilion, which Kodak artfully designed to look like the carousel from its popular carousel slide projectors. (Your grandfather caught it on film, too.) Expo 67 was all about media, and the Kodak pavilion's draw was the 360 degree screen the company installed to show a film intended to surround the audience on all sides. (Alas, aside from an all-enveloping shot of Canadian mounted police I can't remember a damned thing about it.) As much fun as it was, the lines were astronomical. I remember an exhibition called Labyrinth whose queues were literally 4-hours long; there were strategically placed signs along the route that supplied time advisories, e.g., 1 HOUR 45 MINUTES WAITING TIME FROM HERE. Is there anything out there today I'd be willing to stand in line for 4 hours to see? Nothing springs to mind.
