How do you know someone is a grandparent? They've got milk stains on every shirt from burping babies. Their pants are worn out at the knees from crawling around giving pony rides. They have 2,842 pictures of the grandkids on their smart phone and not one photo of their spouse.

I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.
