I don't live in Texas, but I've visited a couple of times.
Pros: Lots of room to spread out, low cost of living, cheap real estate (as long as you don't mind the commute). Best State Fair in the country.
Cons: Long driving distances, hot as ****. Don't expect to find 93 octane everywhere you go (that only applies if you're driving a 1973 MG B through Tyler).
