This is a video from Route 66 east of Albuquerque in New Mexico of a stretch of the road (aka The Singing Road) with a rumble strip that plays ‘America The Beautiful’ if you drive over it at 45MPH (the speed limit). If you drive over at 70MPH? America The Beautiful, chipmunk version. And if you drive over it at 88MPH? Just the sound of lightning crashing and the sound of Doc Brown’s voice in your head, cause you time travelin’!
