For the past several days, San Francisco Public Works has added emptying and cleaning up around trash bins at Lands End, Aquatic Park and Fort Funston to their regular routes.

"We're going to do what we can," said Public Works spokeswoman Rachel Gordon. "We do have other challenges in San Francisco to keep the streets clean, but we have no plans to stop helping out on these parklands as the shutdown continues."

According to Gordon, the extra work might mean it takes employees longer to get to their regular duties, but they will still get done. Gordon said they haven't added any extra crews and are keeping track of the time it takes them to do these additional tasks.

Volunteers say that since Public Works got involved last Wednesday, the condition at the parks has improved somewhat.

"But it shouldn't be city workers, it shouldn't be community members who just can't stand the denigration of their national park," Rep. Huffman said. "It should be folks who are paid to do this work and ready to do this work, and we should open the government so they can do it."

Huffman and Speier gathered the trash they collected at Lands End into two bins labeled "Trump's Trash." They say they plan to bring the trash to Washington D.C. and deposit it at the White House.

"It is a stunt!" Speier admitted. "We're doing a stunt to equal President Trump's stunt."

"I'll tell you what's not a stunt," Huffman added. "It's the diapers and the coffee cups and the burrito wrappers and the trash that's piling up in [National] Park Service facilities all over this country because of what President Trump has done. His actions have real-world consequences."

Some sites run by the National Park Service have been able to stay operational during the shutdown thanks to agreements with private companies or outside organizations. Alcatraz remains open, and Muir Woods will be open through Sunday, before closing indefinitely on Monday, Jan. 7.
