Next year's AWP will be in Seattle, where Kirsten lives, so I am dearly tempted to go. No idea if SF/F books would sell there. But they might. Would people be interested, do you think? Usually we ask you to ship your books both ways, and pay for a cut of the table costs. We don't take a percentage for selling.
(We typically do tables at WisCon, WorldCon, World Fantasy -- that sort of place. Not all of them, not every year -- depends a lot on whether we have people attending who can staff the table.)
