I'm attempting to justify five conventions this year. I already paid for Ambercon and Noreascon, so I imagine I have to go to those, and ComiCon is driving distance and lets me in free. And any excuse for a trip to San Diego, baby. And World Fantasy is in Tempe this year, and I'm trying to talk the boy into coming with me. So I'd be silly not to go, except cost of travel and so forth.
Which actually isn't all that much.
