I liked the Experience but Las Vegas was the wrong venue.
As for the Smithsonian idea, they house pop culture items frequently in the American History pavilion.
Star Trek is the "primo" of pop culture; an entire pavilion, administered by the Smithsonian, dedicated to the world of Star Trek ... is that such a bad thing?
Who is paying for this pavilion to exist? I don't think Star Trek props have the same drawing power that you do.
