It is actually a pretty interesting little book. There is only the one chapter on HOGAN'S SECRET. It is more of book that contains little stories about Hogan.
Another thing he mentioned as part of Hogan's Secret is....BALANCE.
Mr. Kelley, I was told, used one of Hogan's early books, I believe "Power Golf", and a few other books of that time. He studied the pictures, I was told.
