I would watch third-season episodes with my mom (not religiously, but I did make sure to catch the season premiere, "Spock's Brain") when I was 12, Fridays at 10 on NBC, right after season 1 of
The Name of the Game (with that great 7/4 title music by Dave Grusin; see
www.youtube.com/watch?v=hHnoHwZKmlk).
Previous to then, I had never been able to see an episode because of piano lesson conflicts - although I did own (via Scholastic) the first two books of Blish adaptations, so when I eventually saw first- and second-season episodes in syndication, I was sometimes surprised by the differences.
I also bought and cemented together an Enterprise and a Klingon battle cruiser - I still have the saucer of the Enterprise somewhere.
I've been to one Star Trek convention, with some college buddies in January 1975 at the Americana in New York City. Met Mr. Doohan and was floored by the absolute absence of any accent in his natural speaking voice. Saw Harlan Ellison (with shoulder-length hair and a pipe) on a panel. Also saw several episodes in glorious 35mm, including "Mirror, Mirror." Bought a "Phaser equipped / Warp drive powered" bumper sticker for the car, a 1966 Bonneville. Looked at, but did not buy, a bound copy of Walter Koenig's "Infinite Vulcan" script for the cartoon series.
The next year (summer '76) was my first time in Europe, and I'd learned a little German and was pleased to see dubbed uncut versions of "The Changeling" and "Requiem for Methuselah." (Also took home a German translation of Niven's
Ringworld.)
Went to see all the movies through
First Contact and caught up later on the others. Fondest memories are of the premiere-day audience for
TWoK. I also made sure to see the Shatner
Saturday Night Live episode when it first aired in 1986 and wasn't disappointed. The same year I saw Gene Roddenberry speak at a college in St. Paul, MN (my home at the time) - he didn't let on that
TNG was brewing. I watched nearly the whole original run of
TNG but didn't care so much about the various later series.
With no disrespect intended to any and all authors of Star Trek novels, the only one I've ever purchased (right at the beginning of the Drought) was Blish's
Spock Must Die! I've also heard a TNG novel in audio form, involving Q and Lwaxana Troi (and entirely voiced by De Lancie and Barrett) - called perhaps
Q-in-Law? That was more than 20 years ago.
Stuff I own, other than the Blish books, includes the
TMP fotonovel (transporter accident scene deleted and not missed), VHS tapes of "The Empath" and "Is There in Truth No Beauty?" (I'm a George Duning fan, and when I find it I'll post a scan of his 1980 reply to my fan letter), DVDs of the first two movies (director's editions), and a VHS of the sixth movie. With Netflix I'm glad I didn't buy anything else.
I also acquired La-La Land Records' complete original series music set that came out a few years ago. For me, at least, it's excellent value.
