The Three Amigos of Sand Wash Basin, Patrick Brennan, Joe Tosh and John Wagner are three wild life and wild horse photographers that came together through the social network pages of Face Book and began meeting and photographing a herd of wild Mustang horses in Northwestern Colorado for the past three years. Over those years a solid friendship developed between the three photographers. That friendship was cemented by a love and passion for the National Treasure that they photographed on the range of Sand Wash Basin- the wild American Mustang. They came together to write this book that is full of many great stories of their adventures and is chuck full of their collective "Best of the Best" wild horse photographs.
