Ohio State has already opened up its allotment of tickets to the public. Max of 6 tickets, and you can choose either bleachers ($185) of chair backs ($270).
The downside would be sitting in the Ohio State sections – but if you want to ensure you get tickets at face value this is a great way to go. Also, any Ohio State tickets purchased by a Ute is a win in my book.
