Well, this isn't encouraging. StubHub is saying they have 5000 tickets still available for the B1G Title Game this Saturday. Wisconsin has not yet sold all of it's ticket alignment, and there are rumors the B1G or ICC is paying for seat-fillers due to a Craigslist ad. To make matters worse, the ACC title game is selling a lot better on the secondary market: the B1G title game has been selling as low as under $10.
This is why going with the "safe" choice in Indy may not have been a good idea. This hardly would have been a problem in Chicago, despite weather concerns.
