Mexico President Felipe Calderon attended a preview of the travelogue Tuesday night at New York’s Guggenheim Museum. To a crowd of dignitaries and media he explained why he took so much time to take part in the TV program. “There were a lot of risks,” he said. “There was a lot of criticism. People even in my own administration said it was a mistake. But it was an opportunity for me to show Mexico to people around the world.” It’s a show worth seeing.
