There's something particularly breathtaking about the open skies in the west. Yellowstone's geological beauty is amazing, but you get an unfamiliar sense of space when you travel through states like Wyoming and Montana. The openness seems to engulf you and the scale of your surroundings shrinks you. You can drive for 50 miles without passing another car. If you come from living in a city, this kind of isolation may seem frightening or inviting depending on your experiences in cities, but either way its extremely exciting.
