If you haven't read that story linked in the Tweet from Forbes, it's about the Texas Bowl ticket sales going better than any non-playoff bowl. Also, it does not mention Arkansas one time. Not once. It's a two-page story. They seem to think it's all because there's a lot of Texas fans around Houston. Tack this onto our reasons to hate Texas. And Forbes, apparently as well.
Tickets are still available on third party websites and possibly on Ticketmaster as well.
