"Everybody has watched this population decline for generations," says Ryan McMullen, state director of USDA rural development. "There has been a long-term sense of despair, but it now feels this latest drought might be too much to overcome. That's saying a lot for communities that have maintained a population since the Dust Bowl. These are tough, salt-of-the-earth folks that don't call it quits easily." (AP Photo)
