Luis Soriano launched a book-mobile to distribute childrens' stories, poems and atlases to kids living in remote hamlets. Many communities were so far off the grid that they couldn't be reached by vehicles. Another fine point was that Soriano, who earns about $300 a month, didn't own a car. So he built a couple of book shelves to fit onto the back of his trusty donkey, Beto. Now, Soriano bring "Robin Hood" and "Don Quixote" to a new generation of Colombian readers.
