There are many national parks, monuments, and memorials to visit. I have experienced all kinds of weather and crowded conditions at all of them. Another thing they all have in common is clean air, wide open spaces, and the most beautiful scenery that you will ever see. Unfortunately, light pollution is creeping into many of these places. It would be beneficial to all life on earth to reduce the pollution as much as possible. The right lighting can be less expensive and very important for our environment.
