Where in the world can you find a place where when the rubber hits the road. . . . . the road actually sings? In Okinawa that's where. On a small stretch of road off route 331 some genius (as far as I am concerned) has found a way to cut grooves in the road to make it so that when you drive over at just the right speed of 40kph you can actually hear a song. I honestly can't say much more about it because you have to experience it to truly understand how fascinating this is. Below I have a video which is just brief and again it doesn't do it real justice.
