Most Americans I know watched the first moon landing in America. But I was in France when it happened, on a 6-week summer trip with a school group. We landed in Paris, stayed there a few days, then went to a boarding school in Strasbourg where we lived for the bulk of the time. On the way out, we stopped in London, then came home on a ship.
So the moon landing happened at a very inconvenient time of day--about 3 or 4 in the morning, as I recall. There were no TVs at the lycee, but there was a television station across the street, and they kindly consented to allow bleary-eyed American kids to stream in and out all night and morning long to watch the progress, and the landing. We were all, at that moment, particularly proud to be Americans, to watch our guys up there where no one else had been, to know that human engineering and ingenuity had done the job.
The next day was Monday. Without telling the girls, a bunch of us boys decided to dress for dinner. We came down in jackets and ties and said we were dressed for Moonday dinner. The next Moonday we did the same, and kept it up for the rest of our time there (and quickly, the girls caught on and dressed up as well).
Where were you when that small step was taken?
UPDATE: Courtesy of Barry Eisler, here's a cool photomontage of the year 1969. So many important things happened that year, in society and pop culture (like the release of some of my favorite movies, including Butch Cassidy and the Sundance Kid, The Godfather, Easy Rider and Midnight Cowboy, the Stonewall riots, the first Led Zeppelin album and the last Beatles concert, and more.
