How come there aren't any fences around camp greenlake?

Camp Green Lake is designed to be a place of punishment and rehabilitation, where the harsh environment itself serves as a deterrent to escape. The lack of fences symbolizes the idea that the boys are expected to confront their challenges head-on, fostering a sense of responsibility and self-discipline. Additionally, the remote location and the harsh desert conditions make it difficult for anyone to escape unnoticed. Ultimately, the camp relies on the natural obstacles and the psychological impact of its setting rather than physical barriers.
