Driving east on Interstate 70 this morning, I encountered a large flock of greater white-fronted geese west of Topeka, Kansas. Flying north over the highway, they were headed for the Arctic tundra, where they will breed. Of course, multiple rest stops will occur along the way.
Somewhat early, even for migrant geese, the hardy travelers were unfazed by the temperature (27 F), the cloud cover, the snow-covered landscape and a moderate north wind. Receptive only to instinct, they were focused on their goal and (unconsciously) on the future welfare of their species.
If only humans were so determined and "optimistic." Unfortunately, our large brains get in the way, infusing fear and doubt when we face difficult situations.
