Sadly I had to purchase this book as a prerequisite for a test. Of the 80 pages 17 are just a list of climate zones in the USA, 6 pages are an index, another 4 pages are blank, 4 pages of definitions, and 4 pages are of "references to other publications". This leaves you with 45 pages that only seem to reference other material or test procedures. I gave this book a fair chance, but cannot for the life of me see what the purpose of this book is.
Unless you need this book for school or a test steer clear. No real useful information and there are better resources out there.
