It's a good time to be planning your fall/winter garden in the Bay Area, but I'm not clear on the precise planting conditions in Rocklin. My Sunset book (see my response to your post in the Introductions forum) is downstairs, and right now I'm upstairs. Sorry....
A fall garden includes carrots and spinach

and can also include kale, broccoli, brussels sprouts, bok choy or any of its closely related greens, rapini (aka broccoli rabe), beets, parsnips, turnips, chard, and the like. Pretty much root crops (but not potatoes) and leafy greens.
You'll have to be on high alert for snails and slugs, which LOVE the leafy greens. I go out Snail Hunting

and keep their numbers down. After my hunts earlier this year, I've only found a total of 45 or so since mid-June. (Grim satisfaction? You bet.) There may be additional pests in Rocklin, but here in El Cerrito, and before that in Berkeley, snails and slugs were my #1 Enemy for cool-weather gardening.
Hope this gives you some ideas.
