As Americans we have inherited a beautiful land, a promised land. As we travel around our country in the summertime we realize just what a grand inheritance we have received. We have also been a destructive people. We have not taken care of this rich and gorgeous land. We constantly engage in a battle to preserve the environment. We can be grateful for the men and women through the years who have had the vision to create and preserve our national park system that protects our country's wilderness areas from development.
