Remember when the schools weren’t air-conditioned, managing classrooms of 30 to 35 kids under those conditions must have been tough, and two a day football workouts are probably still tough.
Texans lean towards being tough, Sherman was wrong, Davy Crockett was right.
None of the public schools I attended in Texas had air conditioning, but school didn't start until about the 3rd week in September and the windows were about 12 feet high that had to be adjusted with those long poles with a hook on the end. I was a band nerd and we had summer practices at 6 AM which was a good workout on the football field before the heat could kill us.
