California did get a bit of rain recently, but drought remains a persistent problem. And while no one can make it rain, farmers can try to look for more water underground.
To do that, many have been relying on a practice known as "dowsing" or "water witching."
Marc Mondavi is a self-proclaimed water witch. A member of the famous winemaking Mondavi clan, he's also a vintner, and has created a line of wines called "The Divining Rod," a nod to his other line of work. Thanks to the drought, Mondavi has been getting plenty of calls lately.
