What's the biggest audience you've performed for?

Years ago I did public speaking and drama. It was a real rush to get the audience to react to your performance. I guess I let it go because there was more money in engineering but sometimes I wonder... Biggest audience was maybe a thousand for a halloween story entitled, "The Real Thing", I performed up at Saint Cloud College. My favorite though was a one act titled, "An Overpraised Season" where I was the main character confronting his overly religious mother so he could go to a dance with a girl. Also did some shakespear in college. It was fun but got a bit monotonous.
