Isn't This Like A Geeky Rite-of-Passage?

I may be going to a Star Trek convention at the end of next month! I've never been to one, but it sounds pretty neat. I looked it up on the convention center website, but it didn't give a whole lot of details. Any of you guys ever been to one? If so, what sort of things do they do, usually? The website listed things like meeting and getting autographs from cast members, but surely there's more going on than that. Too bad Kate Mulgrew isn't going to be there...she's the main person I'd like an autograph from!

I haven't decided for sure if I'm going or not, but I'm really thinking about it. I'd have to take a day off work (maybe two, depending), and the tickets aren't exactly cheap. But still...I've been a Trekkie for a long time. <3 We'll see, I guess!
