The Fort Mason Farmer's Market in Marin County's Vista Point was bustling with mask-wearing customers who needed a break from being cooped up indoors.
"The cliché of getting some fresh air, it's impossible, but you feel like you're able to breath outside," said San Francisco resident Jenny Lederer.

Organizers did not cancel the market due to poor air quality because so many farmers depended on it. The Sunday before Thanksgiving is considered their busiest day of the year.
" We had requests from farmers who had other markets canceled Sunday so we tried to make space for people on this important shopping day," said Moti Phillips from California Farmer's Market Association.
The poor air quality also forced the Golden Gate National Recreation Area to close Muir Woods and the welcome center at the Golden Gate Bridge, including all concessions.
On Sunday morning, the bridge was shrouded in a mixed bag of smoke and fog.
"We came to see the bridge. Can't hardly see it," said tourist RJ Jamindang.

The GGNRA posted it on its website that attractions like Muir Woods, Alcatraz and Fort Point would remain closed on Monday, November 19 due to unhealthy air quality.
The San Francisco MTA announced that cable cars would not run on Monday.
There were plenty of bikes for rent at Bay City Bikes at Bay and Taylor Streets.
"People left the city because of the smoke, we're waiting for it to be better next week, we'll see," said manager John Akbay.
