I don’t think that too many ordinary folk want to mingle with cosplaying “Trekkies”. It’d be like making a theme park out of Comic-Con.
I’m a big “trek” fan, but I know what you’re talking about. I’ve also done security at star trek cons. There is a subset of the “trek” community for whom the line separating reality from fantasy is either blurry or nonexistent. I enjoy “trek”, but when the TV/DVD player shuts off, I know it’s 2014 and not 2266 and I gotta go to work tomorrow.
