Do I need to quarantine if I travel to San Francisco from New Mexico?

I did, but not for COVID-19

Don't travel unless it's a matter of life and death.  COVID19 is a serious matter.  Real ppl are dying.  The worse thing isn't that the doctors and nurses have to work extra hard with dozens of dying patients.  The worse thing is that you can die in the hospital bc treatment options for COVID are limited.  I am a Republican and I wear a mask.

I drove to SF and there were no roadblocks. I don't know what they will do to you at the airport, unless you parachute before landing.

There is a travel advisory that recommends that you should quarantine for 14 days on arrival in California if it's not essential travel. https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/CO...

Yes you do.    

San Francisco's newest stay at home order begins tonight at midnight (12/5/20) and lasts until January. So I would imagine so.
