We have a comic show here in Memphis, run by one of the guys from Comics & Collectibles, our largest comics shop.
We have a lot of one-day shows in the area. The biggest is probably the one in Charlotte: it's quarterly, organized by a group of local dealers. HeroesCon has had a one-day Mini-Con, too. That's a huge show floor in those photos. It looks nearly the size of HeroesCon's show floor (there are also several rooms for panels).
