i have never doubted macs information or explanations they have always been clear and understandable and backed up by demonstration. alot of people doubt macs book will ever come out, will it ever im not sure, i do know he wanted it to be right and complete and that is why it has takin so long for him. but anyways i do know of another golf writer that took i think 28 years to right his book and im sure homer probably also always thought he was close to it being finished.
