Let the people walk. Or ride horses, bicycles, mules, wild pigs-anything-but keep the automobiles and the motorcycles and all their motorized relatives out. We have agreed not to drive our automobiles into cathedrals, concert halls, art museums, legislative assemblies, private bedrooms and other sanctums of our culture; we should treat our national parks with the same deference, for they, too, are holy places.
