Only two people in this book are not fictional characters: Fran Houser of the MidPoint Caf'e in Adrian, Texas; and Joe Villanueva of Clines Corners in New Mexico. Many thanks to them for the history lessons and for permission to write them into my landscape. And thanks to my researcher Dianne Burke for technical support above and beyond. I thank Richard Hughes for musical suggestions and psychological insights. My brother, Bruce, contributed expertise on camping gear that you won’t find in stores. He also gave me the recipe for cowboy coffee, and helpful hints like how to set fire to wet logs and kindling. Ed Herland was my Porsche consultant, and I could not have done this without him. Thanks, Ed. And thanks to Patrick O’Connell (no relation) for help with roll bars and airbags, and to his father, Dan, for a guided tour of the Seligman loop of Route 66 in Arizona. And a long overdue thanks to the work of E. W. Mitchell, The Aetiology of Serial Murder: Towards an Integrated Model (1997), University of Cambridge, UK. This academic may not appreciate finding his name in a work of fiction, but his excellent paper helped to shape my view of profiling as the dog-and-pony show of junk science. As for The Who, the Eagles, Rolling Stones, Beatles, Bob Dylan, Black Sabbath, Led Zeppelin and all the other musicians, singers and writers of melodies and lyrics- thanks for the road songs.
