Mostly, I want to see if this works. This was taken just after the USU touchdown. This is the most people that were ever at the game.
So, look at a row or two and count empty seats/full seats. The side the picture was taken from did seam to have more people, in all fairness. But there were still plenty of empty seats around us and in front of us and all around.
But I think saying 1/2 full would be optimistic, even before everybody left. 41K is a bold faced lie.
