If you ever find yourself driving between mile markers 4 and 5 on Route 66 just outside of Tijeras, New Mexico then you should slow down to 45mph and let your car drift over the ‘rumble strips’ on the side of the road.
What you’ll hear is an absolutely magnificent and patriotic display of engineering, because once your car hits EXACTLY 45mph and you’re driving over those rumble strips the song ‘America The Beautiful’ will begin to play.
