Monterrey is a tourist zone? Huh? I’m talking about the largest industrial city in northern Mexico, one that’s closely linked to the Texas economy, not Cancun.
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.
