In fact, there is a little known [to outsiders] law that if you are a Texas resident, traveling across at least 2 counties in Texas, you can legally carry a handgun in the passenger compartment of your vehicle without a concealed carry permit. You must immediately declare it if stopped by law enforcement; but, you won't be detained for the weapon possession.
Additionally, unlike some other states, Texas state history is emphasized in its school system. Natives of the state are taught that the term "Texan" came about in Hollywood westerns and stuck with the rest of the country. If you want to get in good with natives (especially older folks) of that state, use the official term that they were raised with - "Texian." Hollywood didn't like it; so, they changed it.
