California is very mild in certain places. I happen to live in the hills up north so we’re not like SoCa. They have totally different weather than we do.
That is like TN, Memphis has much milder weather than they do on the east end of the state, where they get more cold and more snow. We are lucky to see a 1/2” some years. Others we get a foot. Just the threat of snow will close the schools here.
