The huddled masses are still able to visit the Statue of Liberty. The Grand Canyon is open for business. The government says other national parks "will remain as accessible as possible," although some roads at Rocky Mountain National Park are closed as snow goes unplowed.

Utah's state government is paying to staff the visitor centers at Arches, Bryce Canyon and Zion national parks. Arizona is ponying up to keep trails, shuttles and restrooms open at the Grand Canyon. New York is footing the bill for the Statue of Liberty and Ellis Island for the third shutdown in five years.
"Many travelers have planned their visit for months in advance and have traveled from all over the world to be here," said Utah Gov. Gary Herbert, a Republican. "We want them to return home with memories of magnificent vistas and welcoming people, not locked doors."
The shutdown is affecting nine of the 15 Cabinet-level departments, including Interior, which runs national parks, and Agriculture, which runs national forests. About 16,000 National Park Service employees — 80 percent of the agency's workforce — are being furloughed.

It's also closing some of the nation's presidential libraries.
The George H.W. Bush Presidential Library and Museum in College Station, Texas, is closed, but the family gravesite — where the 41st president was recently buried — will stay open. George W. Bush's presidential library in Dallas is open, but archive services won't be available.
Temporary and permanent exhibits at the Clinton Presidential Library and Museum, a top tourist attraction in Little Rock, Arkansas, are closed, but the restaurant is open and offering "Shutdown Specials."
At Acadia National Park in Maine, austerity measures include closing some bathrooms, curbing trash collection and cutting back on snowplowing.
A lack of plowing is closing roads at Rocky Mountain National Park in Colorado, the fourth most popular national park in the country, and the visitor centers are locked. "This is really disappointing," said Sarah Schlesinger of Boulder, Colorado, who went to the park with two nieces from Florida who had never seen snow before.
Unplowed roads also could hinder access to Crater Lake in Oregon, Mount Rainier in Washington and other parks normally inundated with snow this time of year.
Hotels, restaurants, stores and gas stations at Yosemite National Park in California remain open and seem unaffected by the shutdown, which has canceled some programs, closed visitor centers and left campgrounds unstaffed.
"It's basically free to get in the park and people are coming and going as they please," said Jade Lezon, a cashier at the El Portal Market, near an entrance to the park. "It looks like summer today. Perfect weather for a government shutdown."
Superintendent Cassius Cash of Great Smoky Mountains National Park in Tennessee said visitors should practice "leave no trace" principles to avoid fouling up the park when no visitor services are available. The holiday period is typically one of the park's busiest weeks, he said.

Navy sailors operating the tour boats aren't affected by the shutdown.

At the Statue of Liberty and Ellis Island, it was business as usual after New York Gov. Andrew Cuomo, a Democrat, said the state would fund operations, as it did when the federal government shut down in 2013 and in January. It'll cost the state about $65,000 per day, Cuomo said.
"Thanks to New York kicking in the funding!" said Steffen Manheim, a tourist from Maine.
In Arizona, Gov. Doug Ducey activated the state's Grand Canyon Protection Plan, which calls for the state to underwrite the cost of public safety and basic services at the desert treasure. Arizona developed the plan after it stepped in to fund operations during the last shutdown, 11 months ago.
"Regardless of what happens in Washington, the Grand Canyon will not close on our watch," said Ducey, a Republican. "If you have plans to visit the Grand Canyon over the weekend, keep 'em. The Grand Canyon will remain open."
