"Discovery is adventure. There is an eagerness, touched at times with tenseness, as man moves ahead into the unknown. Walking the wilderness is indeed like living. The horizon drops away, bringing new sights, sounds, and smells from the earth. When one moves through the forests, his sense of discovery is quickened. Man is back in the environment from which he emerged to build factories, churches, and schools. He is primitive again, matching his wits against the earth and sky. He is free of the restraints of society and free of its safeguards too."
