Do you have a link for that?
The seating capacity of Alex Box is 10,150.
Tickets sold vs. Nicholls was 11,214. The Saturday Brown game had 10,269 tickets sold. The Friday night game was just short of capacity with 10,085 tickets sold.
So for the weekend the capacity was 30,450 and the number of tickets sold were 31,568. So you don't have to worry about the bond debt not being repaid from this past weekend's schedule.
You can verify all these numbers by going to LSUSports.net. That's where I got them.
