In California, a high-profile lawsuit is seeking to halt construction of a new $500 million rail yard next to the Port of Los Angeles. Activists, including a national environmental group that's spearheading the opposition, say the massive project would mean even more pollution for nearby neighborhoods that already have some of the worst air in the country.

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.

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.

Tenth Street Elementary is in the Pico-Union district of Los Angeles, a few blocks west of the Staples Center and downtown skyscrapers. It's a tough neighborhood; school security is always an issue.

On a recent day, about 150 third-graders were spread across a worn cement playground, running around, playing chase and tag.

Most lunch hours, you'll find Juan Alfayate, the school's energetic principal, out on the blacktop, dodging soccer balls and having fun with the kids while on playground patrol.

Wyoming has the highest per capita suicide rate in the nation. Guns are also a big part of everyday life: The state has one of the highest rates of gun ownership.

It's not hard to find someone in the state who's been directly affected by a suicide in which guns were the lethal means. BJ Ayers has not one but two of those very tragic stories, and she has turned her grief into action.

Guns are a big part of everyday life in Wyoming, and many residents have been directly impacted by a suicide in which a gun was used. The state has the highest suicide rate in the nation, and three-quarters of Wyoming's suicides are by firearm.

The rural state's relationship with guns has long made suicide prevention efforts challenging. But that may be starting to change.

Lax Gun Laws

Last year, there were more suicides in Natrona County than anywhere else in Wyoming.

The soft-spoken county coroner saw them all.

In the West, fights over water last a long time.

It's been almost 100 years since William Mulholland stood atop an aqueduct along the Owens River and said, "There it is, take it." He was referring to a diversion channel that started piping water to Los Angeles from 200 miles away. That water allowed L.A. to become the metropolis it is today.

But it also meant that the Owens River no longer flowed into the massive Owens Lake, which quickly dried up and became one of the biggest environmental disasters in the nation.

Spring has come early to the Yosemite Valley, and the melting snow makes for a spectacular rush of water off the granite face of Yosemite Falls, the tallest in North America.

Early March is when park officials would normally be gearing up for the busy tourist season. Instead, they're figuring out how to cut $1.5 million from their budget. Without a budget deal, the sequestration has forced the Park Service to cut a total of $134 million from sites around the country.
