Maybe when 80,000 fans show up in your 100,000 person town 6 times a year or when 80,000 drunk fans leave your 100,000 person town 6 times a year. :-)
I live in a college town. Of course we rarely to get 1/2 of the fans that OU gets, but I still don’t find it much of a nuicence whether it is 25 or 50 thousand. Just minor schedule and route adjustments, and you won’t even notice it. Besides, once or twice a year it might even be enjoyable to join them. If it was an opera getting 80,000 people, the magazine would be raving about it.
