In Californication, even if the roads are clear they can make you carry chains in the high country. It is not a cheap ticket if you get one. At Yosemite, they don't plow the roads till late Spring.The latest they have done it was the beginning of July. I just bought some SCC Z6 cables which seem to be the cable of choice for a couple of weeks from now I'll be up there. So I'd call or google the rules about the high country. If you want, I'm 20 miles E. of SF and you could send them to me if needed. There are people in Sacramento too.
