Took a gander at your con pics. My God, does Dragoncon have a lot of nice looking ladies each year? I think I'd better stop going to anime conventions and try out a Sci-fi ones, lol. Always wanted to go to a Comic/sci-fi con. Although Dragoncon is in Georgia and that's a bit of a trip for me. Have you heard if http://www.shore-leave.com/ is a good con? Since it's in Maryland, that'll be a much much....so much...closer one to attand, lol. Plus Amanda Tapping is going to be there.
The last "sci-fi" con I attended wasn't exactly what you'd call a convention. More like 2 rooms with nothing much in them except shirts and posters. Really. It was only 2 rooms. A "dealers" room which had only what I mentioned above. And a viewing room where all they showed were previews for upcoming movies in the theatres. The only reason I went was because 2 Stargate SG-1 supporting characters were there for autographs and pictures....which I missed since I got lost.
