Acknowledgements My wife, Jane Vicroy Scott, accompanied me on many trips, and made many sugges-tions about the text and layout. Surpris-ingly, my extended absences while in the field caused her some dismay. Her love and big heart are what nurtured this project. See pg. 294.

About 2800 of the approximately 3700 photographs in this book were taken by the author, but other photographers provided many wonderful photographs that increase the usefulness of this guide. Thanks to all of them for allowing their photographs to be used in this work. I’d like to especially thank Will and Gill Carter, Kim Garwood, Dan Janzen and Winnie Hallwachs, John Kemner, Jean-Claude Petit and Pierre Boyer, and Jane Ruffin, each of whom not only provided more than 50 photographs, but also took the significant time and effort to find the photos and to deliver them to me.
