I owe a big thanks to the members of my book review team, who each volunteered to review all or part of the book and provide input as I developed it. The team included (in alphabetical order) Ellen Boerger, Chahnse Bourommavong, Sheck Cho, Bill Franks (not me, but my dad!), Sarah Gates, Dan Graham, Richard Hackathorn, Bryan Jones, Jack Levis, Bob Sievert, Jeff Tanner, John Thuma, and Scott VanValkenburg. Your terrific input helped me make the book much better than it was before your input. I also owe thanks to all of the individuals and companies that provided me with the knowledge, experience, and examples that enabled me to write this book.
