Sad day for us Star Trek fans. (I've been one since junior high). Leonard Nimoy, who's played Spock for a generation, bids farewell to the conention scene.
I've gone to a couple Star Trek conventions and managed to see the following:
Majel Barrett Rodenberry (Nurse Chapel)
Nichel Nichols (Uhura)
James Doohan (Scotty)
Mark Leonard (Sarek, Spock's father), and
George Takei (Sulu)
Of the Enterprise crew, I've met George Takei the most (three times). In fact one convention held a "Run with Sulu" event--a six miler, set at warp speed. The only guys who could keep up with Mr. Takei was me, a marathon runner and a US Army Ranger. That was a long time ago...
