Free Conventions For Cartoonists

I'm curious how many conventions are out there that offer free table space and attendance for creators. I've mentioned the wonderful Minneapolis conventions FallCon and MicroCon as two examples of this rare practice in the past... they both offer free table space to any creator who asks for it until table space runs out. Josh Blair mentioned Syracuse Heroes Expo, Ithacon and the Ithaca Winter Comic Book Show on my personal blog here. Are any of you aware of any other conventions that do this? Please let us know in the comments.
