Probably lowballing it a bit, but not by much. As I left at 12 noon, there were still plenty of people piling into the stadium.
There was a guy outside in the heat who blew a ram’s horn. He was there at 10AM when i first arrived and he was still there at noon. How he survived the heat, I don’t know.
It certainly generated a great deal of news coverage. I wonder if the guy with the ram’s horn was part of the anti-rally protest. I read that a small group of atheists were outside of the stadium carrying on for a while.
