I ran Arkham Horror with all the expansions including the new Miskatonic and the Dark Pharoah at Strategicon (www.strategicon.net/index.php) over Labor Day weekend. People had a blast with a ton of spectators that stopped by just to take pictures. I also got lucky because Kevin Wilson was one of the Guests of Honor and he graciously signed my main board with "Ia! Ia!" I took a couple pics (below) and was glad that I could share the insanity.
