I love this thread.
In no particular order:
1. Flown in an actual WWI era biplane during an aerobatics routine. The plane was not a reproduction, although it was obviously well maintained. The pilot looked old enough to have purchased it new. Better than any rollercoaster on the planet.
2. Spent every weekend of one summer throwing parties at Jefferson Rock in Harper's Ferry, WV - a national park. The next summer we learned, to our great dismay, that the cop we had befriended (and who consequently 'overlooked' our bon-fire ragers) had been fired. We learned it the hard way, by nearly being busted the first weekend of that next summer. Fortunately the cops never learned to turn off their flashlights when coming up the hill.
3. The first time I met George Takei,
he introduced himself to
us. I believe that it was due to my buddy and I being the only two attendees who didn't mob him as soon as he came offstage. We were just standing and waiting for the room to clear so we could leave, when all of a sudden he pops out of the crowd in the isle and walks down our row, extending his hand. "Hi, I'm George Takei." Maybe he didn't want us to feel left out, maybe he was 'rewarding' us for not leaping in his face like everyone else, or maybe he was just trying to escape the throng and we were a convenient excuse to leave the isle. Any way, it was totally unexpected and very cool.
4. Woodstock 94 and 99. 'Nuff said.
5. Saw Star Wars during it's original theatrical run, in Germany, in a German theater, in
English. The movie started an hour late, and the previews for Close Encounters were in German, nearly causing a riot until the theater manager leapt up front assured everyone that only the previews were in German.
