Natural scenery furnishes the contrasting element to the artificiality of the city. All of us should often run away from the works of men’s hands and back into the wilds, where mind and body are restored to a normal condition, and we are enable to take up the burden of life in our crowded streets and endless stretches of buildings with renewed vigor and hopefulness. (Burnham, Bennett, & Moore, Plan of Chicago, p. 53)
