Which is likely almost as close for fans in San Antonio as the boxes in Dallas may be for those in Ft. Worth (and even closer, considering Dallas traffic). I think there would be less of a complaint if they had done Dallas, Austin, and Lubbock. Though Houston will be the largest US city where no box was dropped (5th largest city).
From what I can see, St. Louis (under 3 million, half the size of Houston) will be the next largest city not to have gotten a BYU box.
