That does sound quite boring. I also don't understand comic conventions. The two types of conventions I can understand are science conventions (people give talks about things that they've discovered, people demo new products, and it's a great networking opportunity) and gaming conventions (because people actually game). Though, I guess road trip conventions are ones I understand, too, because they're actually using their whatever the convention is about (motorcycle, classic car, hearse, etc). Road trip conventions sound much more interesting than comic conventions.
