Any convention is tiring; a WorldCon is exhausting. But, as tired as I am, I'm sad that it's over. I met a lot of interesting people. I had a great deal of fun. I even managed to avoid Disneyland. Mostly.
I'm looking forward to the next couple of years; I think Yokohama will be fun (albeit ten times as exhausting as this one), and so will Denver. Maybe at some point I'll regret volunteering, but I guess we'll see (Nippon2007 in particular is going to be, ah... Interesting is perhaps the right word. Possibly the best and worst ever, depending on who you ask next September).
I also probably shouldn't mention how many times I've been to Jack in the Box in the last week. Or that I'll be going by it one last time for breakfast.
