Putting aside the politics, weather, and economic structure of Texas, the "mystical ethos" of Texas is the thing that really gets me, and I had to leave the state before I could get a good vision of it. The pervasive myth of Texas being larger-than-life, exemplified by the "I wasn't born in Texas but I got here as fast as I could" and persistently quoting "you may all go to hell, and I will go to Texas" is really something, and it seeps into everything. It's like taking American exceptionalism and raising it several more notches.
