Canary Islands residents reviving a centuries-old language: whistling

People on the mountainous Canary island of La Gomera are embracing a centuries-old language used to communicate across long distances: whistling. Before the internet, phones and even modern roads, Gomerians had no way of getting news quickly to villages on the far sides of enormous ravines and valleys. "Pirates!" "Fire!" "We need a doctor!" The piercing sounds of whistling are now a mandatory part of public education on the island. The World's Gerry Hadden reported this story from La Gomera last fall.
