There is no winter in Bay Area…. no Winter as in Russia with its snow or Winter with it rain and bare trees as in Seattle or London. Autumn seems to change just to the spring here. It is the middle of January but you can still see some trees which still have some last green leafs remaining, while at the same time there is variety of new growth.
I like it especially as the real “snow winter” is easily reachable within 3 hour drive in Tahoe or Yosimite area.
