There is something about waiting in line that attracts the science fiction fan. Whether they're queuing up for the latest "Star Wars" three weeks after shooting starts, or placing reservations on new video games so they can be the first people to play another damn first-person shooter, if there is a line to be stood in, it will be rewarded with diligent attention.

Sci-fi people have meticulous, organized, mathematical minds, and the quiet logic appeals to them.

With that said, this means you've got to get where you're going early. The more popular an event, the more likely it is that it's going to fill. That goes double if they're giving anything away.

Curiously enough, a sci-fi convention is the one place in town where there's rarely a line at the women's restroom.
