Another cool spot to add to your roadtrip is Cherry Springs State Park, a dark sky preserve in Pennsylvania. > Astronomers and stargazers appreciate Cherry Springs State Park for the darkness and clarity of its skies, which make it "perhaps the last best refuge of the natural night sky" in the eastern half of the United States. The sky at Cherry Springs has been classified as a 2 on the Bortle Dark-Sky Scale, meaning it has almost no light pollution. Such "truly dark, starry skies are unavailable to two-thirds of the world's population, including 99 percent of people in the continental U.S. and Western Europe". With optimum conditions, 10,000 stars are visible with the naked eye at the park, clouds appear only as black holes in the starry sky, and the Milky Way is so bright that it casts a discernible shadow. https://en.wikipedia.org/wiki/Cherry_Springs_State_Park#Dark_skies https://en.wikipedia.org/wiki/Cherry_Springs_State_Park#Dark...
