Heliotrope Puzzler - 5/28/12

The Puzzler on Car Talk involved a car driving down a Kansas-middle of nowhere road at noon seeing the same crop on both sides of the road, but from one side it was yellow and the other side it was green. Luckily, the Car Guys were explaining the results of last week’s game before introducing the latest. It seems that the crop was a sunflower with a face that follows the sun. I learned another way to explain myself.
