Authors Ólafur Gunnarsson and Einar Kárason drove through America in a 1960 model Cadillac. Alongside them were Jóhann Páll Valdimarsson, publisher and the Cadillac expert Steini í Svissinum. The trip gave them the inspiration to write a book about the trip which came out in the fall of 2006. Alot happened on this trip and the publisher Jóhann Páll wanted to write a book with the title: How to survive a mad trip with four insane guys. The book could be used for teaching in psychiatric studies..
