Edit: You have a last name only a Texan could pronounce ;-)

Similar experience with my family in South and Central Texas as well. They used to go multiple times per year, but never go now. Back then the cartels were more targeted with their violence. Over the past 10-15 years, it has become indiscriminate. A cheap tampiquena plate and a few drinks is not worth the risk.
