Alan Day’s upbringing branded him a cowboy from the day he was born and to this day, claims that he has soil running through his veins. He was part of the third generation to grow up on the 200,000-acre Lazy B cattle ranch straddling the high deserts of southern Arizona and New Mexico. The ranching and cowboy lifestyle appealed to him so greatly that after graduating from the University of Arizona, he returned to manage Lazy B for the next 40 years. During his career, he received numerous awards for his dedicated stewardship of the land. In 1989, Alan purchased a cattle ranch in Nebraska and soon after, a ranch in South Dakota. The latter became the first government-sponsored sanctuary for unadoptable wild horses. He developed and successfully used a herd modification-training program for his 2,000 head of cattle and 1,500 wild mustangs. He and his sister Sandra Day O'Connor co-authored the New York Times bestseller, i"Lazy B: Growing Up on a Cattle Ranch in the American Southwest." Alan also wrote the award-winining memoir, "The Horse Lover: A Cowboy's Quest to Save the Wild Mustangs," about his expriences on the wild horse sanctuayr, and "Cowboy Up!: Life Lessons from the Lazy B." Now retired from ranching, Alan lives in Tucson.
