Query: A writer should at least understand his subject

It is quite apparent that Dr. Peck chose a subject that he is clearly not qualified to write about. I'm not really sure who he is trying to target with this book. If you understand anything about golf you will be bored with his lengthy details of golf terms and basic forms of play. If you are a beginner you will get into trouble if believe that his interpretations of the rules of golf and golf etiquette to be correct. Dr. Peck is quick to point out that after spending over 30 years as an avid golfer he is a terrible player. Part of why he is so bad is that he never bothered to learn the game. Now he thinks he is qualified to write a book about it. There are more great books about golf than any one person could ever read, but this is one that never should have been published.
