Query: Don't buy this book.

This book was poorly written and edited. It's full of spelling and grammatical errors and verbose commentary. The author, in his attempt to impart sage advice to the readers makes defamatory comments concerning a large segment of the motorcycle riding community that he is supposedly trying to serve. He constantly attacks riders of Harley Davidson motorcycles, branding them as drunkards, thugs, and outlaws. Save your money and your time. Don't buy this book.
