It's so weird that, from a central Texas perspective, we used to be a short drive from visiting another COUNTRY, which is now effectively a blank space on the map of the world around us. Ski west in New Mexico, eat easy in New Orleans, Hike north in Colorado. South? Here be dragons.
Maybe the next 30 years will be the same story in the opposite direction, but I don't know. I haven't seen anything to give me hope of that.
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.
I have never visited Mexico and would love to although I will admit hearing things of this sort and some of the footage I've seen of carjackings and machine-gun fire and the like is admittedly somewhat of a deterrent, but then I consider how many scary things happen here as well and I wonder what's true and what's an exaggeration or simply a case of uniquely bad luck.
And I have family that still visits there, but it is much more dangerous than it used to be. 30 years ago it was basically "don't drive a brand new vehicle and be polite" and now it's all sorts of things including knowing which highways to avoid, how to stay away from parts of town that may have drug lord activity, etc. There was almost an unwritten rule years ago that you don't mess with normal people or tourists; that rule has been significantly broken.
And the border waits are much more annoying, too; the people who do still cross now have to wait much longer, even with Sentri.
Sure, the chance of actually being beheaded by a cartel is probably relatively slim, but it's a risk you don't need to take.
I speak fluent Spanish and have traveled all over these areas and I think the original poster’s idea that Mexico is now off limits is about 95% media fear and hype at best.
But hey if they want to stay home in Waco or Uvalde or wherever they live to avoid violent situations that is certainly their choice.
