My friends and I had 25 ID's, but we needed 7 ticket, ended up with exactly that. At the very least they should make you show a student ID at the gate of the dome to get in. This would cut down on people getting extra tickets to sell. I know at the SEC B-ball tourney when they offer discount tickets to students you have to show an ID at the gate to get the ticket.
I think anyone who wants to be entered should have to physically show up at the ticket office, and not have friends scan their IDs. One ID per student.
one of my friends got 9 tickets with 9 id's...how luck was that? I'm glad it was him. He is as hardcore as I am.
