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.

There's great stuff out there, but I prefer doing a TV show, going to work every day with the same people, and a lot of stuff is not being shot in Los Angeles and I don't really want to do that because my loved ones are here.
