In an extreme effort to prevent October wildfires as catastrophic and deadly as those last year, all but a fraction of the sprawling Angeles National Forest has been closed.
No hunting, no hiking, no camping. And for scores - possibly hundreds - of residents such as De Somma, an unprecedented order: No staying put.
De Somma is unmoved.
``I'm not going to leave until somebody drags me forcibly,'' she said, standing in the kitchen of her cabin, which is served only by a narrow dirt road. ``I'm very aware that it's high fire season because it's been like this forever here.''
U.S. Forest Service officials say the people in cabins clustered throughout the forest don't understand how bad this fire season could be. If there are fires anything close to those that burned Southern California last year - when 24 people were killed and 3,650 homes destroyed - they fear people tucked so far into a forest roughly the size of Rhode Island will be killed.
This is the third year the forest has been closed, but the first De Somma and others who live on federal land have been told that, like the general public, they must go.
Already this year, four fires have raced across the forest with shocking ferocity, burning more than 17,000 acres. ``We can't stress enough the danger residents are in,'' said forest spokeswoman Sherry Rollman.
Forest Service officials have persuaded at least some of the residents to pack up and leave. They met with residents of an 80-cabin cluster called Chantry Flats on Wednesday night to explain their reasoning.
Steve Burns, who for 25 years has shared a cabin three miles from the nearest road, said he felt much more comfortable with the order after listening alongside about 35 others to the presentation. Residents weren't happy with the short notice, but planned to comply.
``I think initially they've done the right thing,'' he said, ``but I think we needed a little more time.''
De Somma and other residents don't plan to comply. They insist there will be ample time to flee if fire threatens and they worry that vacant homes make inviting targets for arsonists or burglars.
And anyway, they say, they can look after both themselves and the forest.
De Somma, 49, recalls when car thieves set afire two stolen vehicles in the middle of a remote canyon last year. Members of her community immediately called firefighters, likely preventing a serious blaze.
``For the first time as an American, I feel that I'm being treated like a citizen from a Third World country, with people telling me I have to do something for reasons I don't understand at all,'' she said.
At 680,000 acres, the Angeles National Forest is called the nation's largest ``urban forest'' for its proximity to Los Angeles.
The location is both a blessing and a curse. The forest hosts more than 32 million visitors annually and reaps fees from 1,800 special permits for cellular phone towers, movie filming, dams and campgrounds.
But the heavy public use also makes the forest more vulnerable to arsonists, as well as accidental blazes caused by city-bred hikers and campers unfamiliar with how to handle fire.
Over the past two years, all but a handful of the forest's hundreds of blazes were human-caused, a quarter of them arsons. In response, forest managers have closed the forest to the general public, but let residents with permits for recreational cabins stay on.
The 570 cabins, built in the 1920s and 1930s and now leased by residents, are not intended for year-round living, though some people do just that. About 120 are now subject to evacuation until a major rain douses fire season, among them about 80 homes in Chantry Flats accessible only by up to a four-mile hike into the wilderness. Forest officials said Thursday those cabins are now empty.
Forest officials cite Chantry Flats as a terrifying example. It has no roads for fire trucks and computer modeling shows a fast-moving blaze would block the only access trail, destroying all the cabins in less than five hours _ without even considering the deadly Santa Ana winds that have already started to blow.
But some residents say the fear is overblown.
``When the fire season is over, and it's rainy season, is there going to be a flood order?'' asked De Somma. ``When you really think about it, a meteor could come out of the sky. It's crazy.''
