Those bands you mentioned don't want to play at a venue with seats... They're not the kind of music you sit down and listen to. I saw RBF at Warped in 2002, and just like any other "punk/ska" show I've ever been to, it's so much better to be standing up in front of the stage, with no seats. Hence the reason that Warped brings their own stages to Riverbend, and sets them up in weirder places, and only the smaller acts play on the big stage, under the canopy, which was divided in two. Thats how it was in 2002 anyway. It would be cool though, if KI could get the Warped Tour to come. Except I think it would be in the Picnic Grove.
