Here's a few pictures from the Tulsa rally.

The "home" bleachers were packed from one end to the other. I don't think the planners anticipated so many people because the stage was set up to face the home bleachers, but soon the "visitor" bleachers behind them began to fill up. They were probably 1/2 to 3/4's full and were a rowdy bunch making almost as much noise as the "home" people did. :o)
Yeah, it was great! We were right under the press box (?) on the home side. It was obviously much bigger than anyone expected.
