Boats are seen alongside a pier in a canal at Santa Maria gated community in Greater Buenos Aires in this picture taken on November 29, 2006. Since 1994, an estimated 300.000 people have fled high-density, high-crime, high-priced Buenos Aires and its traditional suburbs near the city core, to live far on the outskirts in pastel houses along idyllic artificial lakes, with 24-hour security guards screening visitors at the perimeter fence.
