Forget apple pie and baseball: nothing says America like our glorious national parks.
And today, the National Park Service celebrates its 100th birthday.
To honor the occasion, we’ve come up with the single most essential experience you’ve gotta try in all 59 of ’em (including every single one in Alaska, where you can throw a coin in the air and hit a new one).
In the words of the Park Service: “Park your car, set the brakes and enjoy the scenery.”
