to be completely honest i cant think of anywhere in the venue that would accommodate disabled seating. don't hold me to it but nothing comes right to mind.
reminds me of a slightly inappropriate story. For a long time i went to Ozzfest every year at the gorge. There was this rocker dude who would show up in a wheel chair and crowd surf...... in his wheel chair. Bands loved to pull him up on stage. I always thought it was cool!
