I'm in Anaheim at my first WorldCon. The official opening ceremony is at one. So in the interim, I've had a chance to catch up with a couple of friends, Mighty Dawno of the Sparkly Ears and Medievalist. It's always wonderful to put faces and voices with people you know and admire from online acquaintance.
Based on this very limited experience, though--if you get a chance to do a big con, jump on it! I'll keep y'all updated as the week progresses.
