Speaking of the Orange, back when I was at Syracuse in the early eighties, the Carrier Dome had just opened, and Big East basketball was just becoming huge.* It became routine to have crowds of 30,000+ for a basketball game. As students we camped out overnight for season tickets, usually starting about 24 hours before they went on sale. Some combination of pizza, frisbee, and Jack Daniels kept us going through the night. At some point in the wee hours of the morning they would typically let us into the Dome to wait in a little more comfort. Fall weather in Syracuse can get pretty cold.
* Remember the epic triple-overtime win against Villanova, in the finals of the first-ever Big East tournament? That was in the Dome, before they started having the tournament in Madison Square Garden every year.
