@Cody L.  100 years plus for most of the upper inland empire land plays.. and yes most likely someone bought it at tax sale. there are companies that churn this stuff for a living most based in LA.

With the internet, you can create opt-in landing pages with eBooks and other free tools for your clients in exchange for an email address.

And while I built my empire to be able to help others, I do what I can to be of direct help to others in need by donating "valuable" and "not so valuable" items to families in need.
