Fake? When I went to Sci-Fi conventions I always carried a real gun, disguised as a fake gun. A little contact cement on the cut in the "peace" knot and I'm not worried. Besides, I never went to a Star Trek only convention.
I was talking about the goofballs who dress up as klingons and such, specifically. Watch the documentary Trekkies sometime and you'll see what I'm talking about. They are a whole different breed of humanity.
What cons did you go to. I usually went to the ones in the Chicago area (Capricon, Dukcon, Windycon.)
Yes Firefly, Babylon 5 and Crusador were great. I do like the new Battlestar too.
