It's a relief to be watching the rain clouds pass over Northern California, where I live, for the next few days. Unfortunately, say weather experts, we may not get enough rain this winter to fend off the worst drought in 20 years. That's bad news for the rest of you, too. California farmers, who grow the majority of America's fruits and vegetables, are leaving thousands of acres bare, for fear they won't be able to water their crops later. That means you'll probably be paying more for your produce this year, starting this spring.
