Again this year, I drove over to the Delaware Bay and Eastern Shore of Maryland to watch the annual migration of snow geese. In a good year, which this year was, the sight is awesome, overwhelming, amazing, or whatever adjective you may come up with. I have stood beside a lake at dawn and seen tens of thousands of snow geese rise up as one body. Every individual goose seems to be honking at once, as if in ecstasy. The morning sun reflects brilliantly as they whirl and swirl.
