JMO but my first reaction was that's ridiculous. Part of the essence of Texas High School Football is the weather from sweatin to freezin. The pros play in enclosed stadiums. But the UIL want's to insure itself against the possibility of an end of fall ice storm, in Texas? Then I thought, it's probably a decision to give the UIL and schools involved the most exposure. A good thing for the schools I guess.
Then again all of the places mentioned have excellent facilities, restaurants, accommodations etc.
