Bill has written several books, including Wild Montana, published by Falcon Publishing in 1995, along with numerous articles about wilderness areas based on his extensive personal exploration.In addition to Hiking California's Desert Parks, Polly and Bill have coauthored several other FalconGuide books, including Wild Utah (1998), Hiking New Mexico's Gila Wilderness (1999), and Hiking New Mexico's Aldo Leopold Wilderness (2002).Decades ago both Bill and Polly lived in California close to the desert-Bill in Bakersfield and Polly in San Diego. They enjoyed renewing their ties with California while exploring the state's desert regions for this book. Months of driving, camping, and hiking, with laptop and camera, have increased their enthusiasm for California's desert wilderness. They want others to have as much fun exploring this fabulously wide-open country as they did.
