Here’s a classic New Zealand scene if there ever was one. In a country built on grazing sheep it’s not uncommon to encounter a farmer pushing his herd down the public road with the help of a truck and a couple stringy sheep dogs.  Cars give way.  I don’t know why, but sheep have a funny way of spiraling when pushed–counterclockwise, in this case, but I haven’t watched enough herds to know whether that’s always the case.
