Rural Tulare County, Calif., is now being called the epicenter of this drought.That's because at least 1,300 residential wells have run dry, affecting at least 7,000 people. When your taps start spitting out air here, Paul Boyer and his team are who you call.Under a punishing midafternoon sun, Boyer helps muscle down five of these hefty 400-pound water tanks from a semi-truck flatbed. He helps run a local nonprofit that's in charge of distributing these 2,500-gallon water tanks to drought victims.
