You can find an announcement for the Cincinnati event here.
To register you need to use the "Register for Events" button at the top, some people have reported that the post is a bit unclear; I think they currently have AGoT listed in the Board Games section, we'll see about getting that fixed. We're having a joust event, no melee though. If anyone who comes to town arrives on Saturday and is looking for something to do, we may be having some casual Thrones stuff in the evening, possibly playing the board game, I'm not going to pretend we haven't had drunken Kingsmoot games before, etc.
Hope to see as many people as can make it!
