I just finished this book, with highlighter in hand. You see from page one where City Zip's name is changed to Zip City, to page 62 where horses have good confirmation to page 80 where Codex is a beautiful chestnut colt to page 84 where Devito is concerned with the breeding fees for Genuine Risk to page 87 where a jockey stood up in the reins to page 108 where Marfa is now a filly running in the KY Derby in the wrong year to page 264 where Bob & Beverly Lewis own Real Quiet... Well, you get my drift. This book is so full of inaccuracies you begin to question the authenticity of everything. Hasn't McGraw Hill ever heard of fact checkers? Don't waste your money unless you want to use it as a trivia game -"How many errors can you find in 10 minutes?".
