Obviously, the term "state park" is used pretty loosely in CA. I'm sure these places all have value, but better to close them than areas that allow the public to experience the outdoors, IMO.
All of these places slated to close in Sacramento area require guards with salaries, security systems, janitorial staff, etc., etc.
(From Sac Bee)
In Sacramento, five of six state parks would close. Besides Sutter's Fort and the California State Capitol Museum, the plan envisions closing the Governor's Mansion, the Leland Stanford Mansion and the State Indian Museum. Old Sacramento State Historic Park, including the California State Railroad Museum, would remain open.
