37. Eat S'mores in Yellowstone National Park

Yes, you can go camping anywhere, and yes you can eat s'mores anywhere, but why not do it in one of the loveliest places in the US in Yellowstone National Park. The first national park in the world (created in 1872), Yellowstone is home to Old Faithful, the famous geyser. It might be pretty commercialized but that doesn’t mean it shouldn’t be recognized as one of the things to see in the US before you die.
