An indoor mask mandate is now in effect in Santa Cruz County and it covers private settings like a home. If you are getting together with others who don't live in the same household the county says you should mask up regardless of vaccination status. Businesses are also required to follow the guidelines. You can take off your mask when eating or drinking.

That was technically the rule in my state last year. They also "highly recommended" eating outdoors. In the snow and rain and freezing cold.
I had some family over who were kinda pricks about the whole WuFlu restrictions thing, and I briefly considered enforcing the rule.
