Lots of place in flyover country or in the deep south where there are no taco carts. I go to Helena MT quite often, no taco carts there. Unless I am looking at the wrong places. So, yes, such places do exist.

I can’t wrap my head around why fast food “Mexican” places survive when there are trucks and taqurias on almost every corner here where I live in Northern California.
Because most Americans are not food curios, much less intrepid. On a food board like HO we are surrounded by people who are not only open minded about food, but actually want to explore and experience different foods and food experiences. Most of the people IRL, are not so inclined. It’s why McDonald’s basically prints money, when your corner mom-and-pop burger stand flipping actual chargrilled burgers come and go and probably wouldn’t survive if not for “cheap” labor.

*I sometimes went to Jimboy’s when my son played soccer in Placer County. Interesting.
Jimboys was good a while back but not so anymore.
