This is a neat place to browse if you're from Sacramento... and would like to go back in time. Check out http://www.sacramentohistory.org/ & the California State Library collection.
Other neat info sources:
PBS has a show on sometimes call Viewfinder that tells interesting local stories. There's also a local guy who's publishing photo history books of local neighborhoods. I'm waiting for the Southside Park book to be released next month so I can buy it. http://www.arcadiapublishing.com/
