My mother-in-law has a cabin in the Poconos. For someone like me who lives in one of the worst suburban locations on the planet for night sky viewing (between Washington and Baltimore), it's absolutely breathtaking. The Milky Way is easily visible, there are so many stars that I can barely recognize anything, and there's such a variety of brightness among the stars that the sky looks three-dimensional.
