Three years after an earthquake devastated Haiti, many residents are still trying to pick up the pieces. Over 300,000 still live in tent cities like this. That's a far cry from the 1.5 million left homeless after the quake, but aid groups admit there's a lot of work to be done. In 2010, the powerful magnitude 7 quake ripped the country apart, leaving hundreds of thousands dead and infrastructure devastated. Not even the presidential palace escaped.
