In my attempts over the years, I have enlisted the aid of people who should know better. My friend Gordon Leisch, who just turned 80, couldn’t figure it out. But he took it to his nephew, Hank, who shoes horses for a living and loves to hunt, who did it in no time flat. Gordon paid attention, but by the time he was relating it back to me, he couldn’t remember. The two of us worked at it for about 20 minutes in the heat out in front of his house before we gave up.
