Much of the material presented herein has been thoroughly controverted in front of university audiences, in corporate conference rooms, and before countless service clubs. Over a period of thirty years thoughtful challengers -- too many to name -- have contributed ideas.

• In New Haven, a well-coifed University Club member raised her hand to suggest that battery-powered underwear might be the best way to make winter bicycling endurable, especially for women.
• Unemployment has nothing to do with oil, said a Kiwani at the speaker's table in New Jersey. We gotta quit paying people not to work. There are plenty of jobs for people who are hungry enough. Pass the butter.
• Commuting by bicycle is eccentric, clearly not appropriate for adults, according to a corporate vice president in New York. "It’s OK to be a wild duck as long as you fly in formation."

Among David's many recommendations: "Forget complete sentences."  Finally, without Jay and Gail Rochlin, Lee Barker and Leslie Johnston, no book.
