Andrew Herrington slips on a battered green backpack, stashes a .308 bolt-action rifle under his arm and steps off a boat onto the steep, rocky shores of Great Smoky Mountains National Park.

"It's about a half-mile that we're going to walk up to for those traps," he says.

In almost every circumstance, hunting is strictly forbidden at national parks. But there's an exception to that rule. Herrington's job is to hunt at Great Smoky Mountains National Park for an invasive and hugely destructive species: feral hogs.

Voters supporting Donald Trump and other candidates turned out in huge numbers yesterday in Arizona, Utah and Idaho, where one line into a caucus site was reportedly longer than a mile. NPR's Nathan Rott waited it out with Arizona voters last night.

When Bernie Sanders took the stage at the Twin Arrows Navajo Casino Resort late last week, he became the first presidential hopeful since 1999 to campaign — in person — on the largest Native American reservation in the United States.

No matter where you are in Tucson, Ariz., you're no more than 20 miles from Saguaro National Park. The park and its tall, pronged, namesake cacti literally surround Tucson. There's the rounded top of the park's cactus-studded Wasson Peak to the west, the park's desert-to-forest Rincon Mountain Range to the east and about a million people living between.

But if you go around Tucson — to its historic barrio neighborhoods, swap meets or hiking trails — and ask people about their neighboring national park, you might be surprised.

"Saguaro High School?"

Driving through the gold-brown savanna of Joshua Tree National Park in Southern California, past its Dr. Seuss-like trees and water-carved rocks, it's easy to see why the national parks have been called America's Best Idea.

Spend a few hours with some of the park's employees, like Cultural Resources Branch Chief Jason Theuer, and you'll see that national parks are also another thing: expensive. There is a nearly $12 billion maintenance backlog of work that needs be done but isn't because of limited money.

A New York judge will weigh in on Wednesday whether fantasy sports is based on skill or chance.

New York's attorney general's office has filed lawsuits against the two biggest daily fantasy sports companies, FanDuel and DraftKings, demanding that they stop taking bets in New York because their games are based on chance, which makes them gambling and illegal under New York state law. Daily fantasy sports companies insist that their games are legal because they're based on skill.

New York state's attorney general has ordered the two biggest daily fantasy sports companies to stop accepting bets there. He says those games constitute illegal gambling under state law.

In making the announcement, New York Attorney General Eric Schneiderman says the games "cause the same kinds of social and economic harm as other forms of illegal gambling" and mislead consumers:

The greater sage grouse is a peculiar and distinctly Western bird. It's about the size of a chicken and about as adaptable as the dodo bird, which is to say it's not very adaptable at all — at least not in a human-driven time scale.

In biological terms, the greater sage grouse is perfectly adapted for its habitat: the rolling hills of knee-high silver scrub that's sometimes called the sagebrush sea. It's the oft-forgotten parts of the fast-changing West — The Big Empty, as settlers used to call it.

The Fish Creek Fire in Interior Alaska isn't much to look at. It's about 7,500 acres in size, sitting about an hour south of Fairbanks near the twisty Tanana River. The main fire front — the made-for-TV part, with torching trees and pulses of orange heat — flamed out more than a week ago, leaving behind a quiet charred landscape.

"Extreme." "Unprecedented." "Historic." Those are just a few of the words being used to describe the start of this year's fire season in North America.

The wildfires are centered in the northwest of the continent, but their consequences are far-reaching. Thick smoke has blanketed parts of Wisconsin and North Dakota. It's triggered air alerts in Minnesota and Montana and muddied skies as far south as Tennessee and Colorado.

And, of course, things are even worse at the source.
