A boy rides his bike in front of the placard of a building in downtown Santiago in this December 28, 2006 file photo. Dozens of glitzy residential tower blocks are being thrown up in what were once quiet, leafy suburbs of low-level houses in this city of 6 million people. Santiago's business district has been dubbed "Sanhattan" due to its supposed resemblance to Manhattan, the New York island of vertigo-inducing skyscrapers. Picture taken December 28, 2006.
