Bangkok prepares for floods

Beside a wall of white sandbags that has become a front line in Thailand's battle to prevent an epic season of monsoon floods from reaching Bangkok, needlefish swim through knee-high water inside Sawat Taengon's home.

On one side, a cloudy brown river pours through a canal diverting water around the Thai capital, just to the south. On the other side, homes just like his are unscathed.
