Not because it was so good, which it was, but where it came from. Most of the food was grown or raised on local farms, or yards. The house we rented had a small front and back yard, but there was no grass. Just about everything growing in the front yard was edible. The trees were Lemon, Fig, and Pomegranate; and the rest of the area was a vegetables and herb garden. The back yard was edible too, chickens. Most of the food that the locals ate came from their yard or within a hundred miles. That made an impression on us and we have attempted to grow a garden ever sense.
Compare that to our local grocery store. I recently surveyed the produce section of Lowes to see where it all came from. I found that most come from the U.S., but 35% come from 6 other countries; the furthest being China. Interesting tidbit was even though the area around Las Cruces grows onions, they do not make it to our shelves . Ours come from Colorado, California, Mexico, and Peru. Next time you go to the grocery store, pick up a clove of garlic and look to see where it comes from. That day in Lowes the garlic had traveled over 6,500 miles to get to our shelves. How green is that?
