You fuckers better have extra fun while you're there to make up for the fact that I can't go.
If anyone has a chance to do True dungeon, it's worth a try.
The Gamer Olympics is always fun, I also recomend that.
If Looney Labs is running "I am Not A Werewolf", I also highly recomend that, it's fun. Just watch your time, my brother did it for 20 hours straight a couple years ago.
Also, my buddy Nate showed me a fun thing to do at Gencon four years ago: When walking by the Palladium booth, yell "CLAP IF YOU WANT RIFTS D20!" when there's a line there.
