I think its at the verizon amphitheater outside of KC. that looks like the layout of it since its an outdoor venue... taken at Summer Jam maybe? I'm not sure tho I'm not seeing many KC hats in the crowd.
Paid Dues wasn't until March 28th, and I could've sworn they had this picture on theReal and the MySpace for more than a month before Sickology dropped. *Shrugs*
