There's all sorts of skiers and even boarders who do the Northern Sierra when there's snow. You'll see dozens of bc adventurers about Donner Summit and other places on a good weekend. We have Sno-Park, and when the snow is great, there used to be full lots and problems finding parking.
I do Castle, Round Top, Ralston, Rubicon, Donner/Judah, and once upon a time, Pyramid. Fairly easy summiting and a thrill ride down, telemark, stem, parallel, your choice of technique.
Way back when, you could ski with a group when we had that in the MLC SC, and I'm still looking for partners. A perfect winter day with coffee, breakfast, bag lunch or thermos, and a fine dining op at one of so many eateries. Home to a nice warm soft bed if you prefer to snow camping or what.
