Acknowledgments After a certain point, writing acknowledgements becomes more difficult than writing the book itself. I’ve reached that point. I’ve stared at this page longer than any other one in this book. It’s impossible to thank adequately everyone who contributes, directly or indirectly, to something like a book. So I won’t. Well, okay, I will a bit. Thanks to everyone at Delta Dental. I had a great experience, and it was an honor com- ing back. To the faculty at UWSP, thank you for welcoming and helping a new faculty member. Thank you Ken Brown and Gary Schwartz; it’s been a pleasure working with you both on another book. Thanks to everyone at Ski’s, for providing the best of the best in both food and service. Of course, no acknowledgements section would be complete without a thank-you to Patti, Jess, Rob, Jim, and Tim at Partners, without whom these pages would have taken longer to write. And always, thank you Kent Laabs for keeping my gear habit going. Looking for- ward to the year.
