The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Dr. Greg Zacharias, former Chief Scientist of the United States Air Force (2015-18), explores next steps in autonomous systems (AS) development, fielding, and training. Rapid advances in AS development and artificial intelligence (AI) research will change how we think about machines, whether they are individual vehicle platforms or networked enterprises. The payoff will be considerable, affording the US military significant protection for aviators, greater effectiveness in employment, and unlimited opportunities for novel and disruptive concepts of operations. Autonomous Horizons: The Way Forward identifies issues and makes recommendations for the Air Force to take full advantage of this transformational technology.

“Personable characters and superb storytelling make this an excellent choice. . . . Essential for Pern fans of all ages.”—Library Journal (starred review) The son of a miner, Kindan has no expectations for any other life. He loves his lessons with the camp’s harper, but music isn’t part of a miner’s future. He also enjoys helping out with the camp’s watch-wher— a creature distantly related to dragons and uniquely suited to work in dark, cold spaces—but even that important job can’t promise a future above the ground. Then disaster strikes. In one terrible instant, Kindan loses his family and the camp loses its watch-wher. It will take a new friendship and a new responsibility to teach Kindan that even a seemingly impossible dream is never out of reach . . . and that light can be found in the deepest darkness. “A guaranteed pleaser [in] one of SF’s most splendid and longest-lived sagas.”—Booklist “Another delightful entry in the Pern series.”—Publishers Weekly
