Of all the experiences I had while living in Peru as a student, by far the most amazing was seeing the night sky from high in the Andes, where the atmosphere was so clear and dry, and the stars so bright and close, that it was overwhelming. Years later I experienced something akin to this (though nowhere near as intense) in Belize. The International Dark-Sky Association is seeking to educate policymakers, planners, and others about the beauty of the dark sky and the light pollution that is making it more and more rare. In Cherry Springs State Park in north central Pennsylvania, the Milky Way can still be seen, according to an article in the New York Times (9/14/07), and people are flocking there to see it. "Chip Harrison, who manages Cherry Springs and seven other state parks, said only 10 percent of the United States population has seen a true dark sky, but a growing number are doing so at Cherry Springs."
