My purpose in possing the question was only partly for my own information. A description of the convention's activities here might help attract some more participants. Apparently modeler's know all about it, but it is less well understood by the non-modeling narrow gauge railfans who might find it interesting. I've been hearing about it for years, but never have seen anything that actually described what it is. The URL helps, but the internet site is pretty basic with regard to information. My guess is there are a bunch of "social" activities that don't show up in the official listing. Like the Dead Goat Theatre and that sort of stuff.
