Just got my program the Carnage 14 convention: Carnage in Wonderland. The event is at a cute Lake Morey Resort on Lake Morey. I went to this event two years ago and the Resort is usually sold out for this event 1 year in advance so you will likely need to stay at one of the bed-n-breakfasts in the area. Their selection of games is quite diverse and there are some unusual games and game variants going on including a homebrew Star Wars 3D fighter combat game, Power Grid: Quebec, and a "double blind" Axis & Allies where you do not see an opponent's forces until you attack.
I have not decided if I will attend because it is 2+ hour drive. They do have a 10 hour session of Advanced Civilization which will always pique my interest.
