I was never a Star Trek fan, BUT I'll tell my Star Trek story.
I was in junior high or high school when the series first started. They must have been filming at Desilu because that's where my dad was working then. He'd see the actors in costume and would mention to me the guys with the funny ears. I'd heard about them so many times that by the time the show aired I thought, in true cynical teen style, "Oh, the guys with the funny ears" and dismissed it.
However, my dad had brought home a number of Star Trek scripts. I'd been reading scripts since I was about 6, so that was no big deal. I still cringe when I think about this: I threw them out!! Yes, I had two or three of the original Star Trek scripts in my hands and I tossed them. Ugh! But nobody knew how popular the show would be or how collectables would appreciate. This was long, long before ANTIQUES ROADSHOW and collectables were a very limited market indeed. There aren't a lot of things I truly regret in life (things I had control over, anyway), but that is one of them.
