How is it possible to be that white in Texas?
Well you're talking about Austin, Texas. It's an island of tree-hugging hippy liberalism. It's a stain on what would otherwise be the best place to live on the planet. Everything is a little bit different there. You're more likely to find freaks in the stands on gameday.
You want Texans that look like Texans? Go watch an Aggie football game.
