the people in the Pavilion were very... well behaved? just all sitting down.. ok kinda lame, but I think Ravinia has memberships where members have early access to tickets. There were a lot of people who just didn't seem like the usual crowd at a Robert Plant show. I am not kidding, I was in the front row to the left and the man next to me was sleeping! and the wife was checking her phone the whole time. I probably should have moved to to sit by the lady who was one of the few who stood up and btw, played air guitar the whole time. At least she was having fun! The encore was awesome.
