Imagine walking barefoot along the shore, wading among the arrowheads. You're feeling through the mud with your toes, looking for tubers for dinner. There was a time. Now we just go to the market and grab a bag of potatoes. And the market has all the flowers in just one small area, if at all. There was a time.
