Lived there for 18 years before retiring and moving to sw Idaho. My main reason for relocating? The older one gets, the less you appreciate having to shovel snow! Before a southern Californian or even someone from the SF Bay Area makes a move to Plumas County, I would suggest you consider buying a snow blower on your arrival or keep a good chiropractor on retainer from November through March. Other than that, you could not find a more peaceful place to live. And I must admit a 5 1/2' snowfall overnight is an awesome sight as long as you don't have to get out in it!
Plus in Quincy, California, at least you will find those of Hispanic, African-American and Chinese - all of whom have been there for years and many of whom are regarded as pillars of the community. For me, it's a lovely place to live from April through September. The rest of the year, I'll take sw Idaho.
