I've spent a significant amount of time in most states east of the Mississippi. A while ago I went to Texas for the first time outside the confines of an airport.
Texas is maybe the worst state I've been to. "Maybe" because I'm deciding if Louisiana is worse, excluding Nola.
If you hate pervasive Republican/conservative/Christian ideology, you will hate Texas. If you hate Libertarianism, you will hate Texas. If you hate car-dominated transit, you will hate Texas.
The best thing about Texas is tacos and general Tex-Mex food. Not a huge endorsement of a place if its best attributes are its external influences.
