I got to go to a Con about 10 years ago here in Victoria. First of it's kind here and unfortunately, the last. Financially, it was a bust so they never tried again. It was pretty cool and I got to meet Dirk Benedict, some Star Trek personalities (Marc Alaimo aka:Gul Dukat for one) and it was a really great time. Too bad we just don't have the population and/or interest to support a gathering like that on an annual basis. Had a blast. My ex-roommate has been to the Diego Con a few times (He's an avid comic collector, writer, artist) and has nothing but good things to say about it.
Cheers
