Planet Comicon has been going in Kansas City for twelve years.
A smaller show, this year sees its April 6th and 7th show moving to a much bigger facility.
A few weeks ago Wizard announced they were doing a Wizard World St. Louis show, three hours East of Kansas City, the week before Planet Comicon.
A few years (and a different mangement team) ago, I understand they floated the idea of putting a show in Kansas City on the exact weekend of Planet Comicon.
This at least is a step up. Ish.
