What it looks like in person? The first time I walked in, I was overwhelmed. I literally felt as though I was walking the corridors of the Enterprise, it's almost indescribable.
For someone who, as a kid, dreamt of walking those halls and never imagining it would come true..well, I was definitely tearing up a bit. I've seen it have that same effect on many others in the times I've been since. Add to that the fact that you're surrounded by so many other like-minded people, and it's just pure bliss. For me, one of the best places on Earth.
