Chester, hopefully this isn’t a dumb question but living where I do the border with Mexico might as well be on another planet. I’ve only been at the border once in Nogales, AZ back in the mid to late 80’s I think it was and found the whole experience very uncomfortable. Didn’t go back and won’t.
Was the area you went too mostly Mexicans or folks of Mexican descent? If so, could it be that they’re OK with what is happening?
