BayCon, which I attended as a vendor this year and haven't seen since 2006, has gotten really small. A big part of that is the generation gap you mentioned; they are aging themselves into irrelevancy, and they don't appear to be making any effort to change that. One thing they could do that would make a huge difference is to court the furries. There's no furry event that weekend, and the other cons that are competing with BayCon for that weekend (a gaming con, an anime con, and a steam con) aren't directly furry, so if BayCon made an effort to invite the furries in, they would see a substantial increase in attendance. Furries are young and enthusiastic, and there are a LOT of them in the Bay Area. BayCon needs to invite them back if they want to continue as a viable convention. It's the only solution I see, unless they move which weekend they hold the con, which is extremely unlikely.
