I personally think where you live is a mind set, and Texans have a solid mind set and don't hesitate to talk about it. I spent 6 months in Texas during my military training, boot camp in San Antonio, Tech school at Wichita Falls. We lived in open air barracks from June to July and air conditioned from July to October. I didn't notice the heat I think because of my age. It seemed hot but you got used to it. Then after service, marriage, child raising years both my daughters ended up for 3 years in Bryan College Station, we visited 5-6 times.
The only time I noticed the extreme heat was one August. From Sept to April temps were warm to mild, went through the ice storms and the torrential rains with minor flooding. Dealing with the fire ants, rattle snakes, feral pigs and killer bees is second nature to the residents. They have a lot to brag about and I would live there if I hadn't become accustomed to the milder climate of the north west, but that's just me.
My wife whom is very adaptable only comment was on our way home one trip we were traveling along I-10 towards El Paso, you go through some of most desolate country imaginable. At one point somewhere in west Texas she turned to me and said, 'And we fought the Mexicans for this?'
