I would die... well not really but close enough... to meet Leonard Nimoy, DeForest Kelly(RIP), James Doohan(RIP), William Shatner, Walter Koenig, Nichelle Nichols, Majel Barrett, Ricardo Montalban, and George Takei from TOS. Patrick Stewart, Jonathan Frakes, Brent Spiner, Marina Sirtis, Whoopi Goldberg, and Michael Dorn from TNG. Pretty much the entire cast of DS9 especially, Nana Visitor (I would probably be so awestuck though that I wouldn't know what to say), Rene Auberjonois, Avery Brooks, Alexander Siddig, and Terry Farrell. That's it for now.
