I suspect the oddly worded (but clever) subject led many to not open your thread.
There are so many CGs out there, you should have no trouble finding one that meets your wishes. My favorite tool is Campground Reviews. Here is the link to CA CGs: California Campground Reviews - The Best of California Camping - Campground Reviews
Just choose the area to zoom in on (scroll your mouse), click on various ones and check the reviews and their websites till you find one that sounds good.
Other good tools (there are many more) include Good Sam, Compendium RV Camping, All Stays, RV Parky, USCAmpgrounds, even Trip Advisor. There are many specialized sources too, many memberships, etc., such as Boondockers Welcome, Harvest Hosts.
Sorry I can't really help you around Sacramento, but you clearly have plenty of choices within 100 miles.
