The candidates have spent a record amount of money. They've stumped hard in a city that isn't easy to campaign in — 470 square miles sliced up into neighborhoods divided by a web of freeways.

Yet despite nearly $20 million in spending in the March primary alone, turnout is expected to be low next Tuesday in Los Angeles when voters go to the polls to pick a new mayor to replace the term-limited Antonio Villaraigosa.

As a result, City Councilman Eric Garcetti and his opponent, City Controller Wendy Greuel, are engaged in an all-out blitz for votes across the sprawling city.

Four people will share the reward money associated with the capture of former Los Angeles Police Department officer Christopher Dorner. He was the cop who went on a killing spree after being dismissed from the force.

A cruise run by the Aquarium of the Pacific in Long Beach, Calif., sounds like a picturesque summer outing. But the Urban Ocean boat cruise highlights the juxtaposition of a powerful port with a fragile ecosystem: You're just as likely to see trash as you are to see marine life.

In front of the aquarium, school kids are running around, eager to go inside and pet the sharks and see the penguins. There's also a marina, where a small passenger boat called the Cristina shoves off from sunny Shoreline Aquatic Park.

The Salinas Valley in Northern California grows about 80 percent of the country's lettuce, and it takes a lot of people to pick and pack it. In a field owned by Duda Farm Fresh Foods, a dozen lechugueros, or lettuce pickers, are bent at the waist, cutting heads of iceberg lettuce. They work frantically to stay in front of a line of 12 more packers, who seal them with tape and toss them onto a conveyor belt.

The Republican National Committee is holding its spring meeting in the Democratic stronghold of Hollywood this week — part of an effort to broaden the party's appeal.

So far, there are sharp divisions among RNC delegates about the future direction of the GOP. But there's general agreement that the party isn't effectively communicating its message.
