I glad to see that folks on this thread -- one of three on the subject -- actually seem to get it. The problem is not with the wind and rain but the massive displacement of up to 2,000,000 people. Perry wants the Austin hotels freed up for evacuees and there is talk that the campus itself would house people (Erwin Center I guess, maybe Greg Gym).
Sure we could play the game in the storm, but everybody from Dallas, san Antonio and Houston couldn't be there because all the roads will be closed or jammed. Not every UT ticket holder lives in Austin and Dodds is at least aware of this.
