Thank you for the links.

Public officials are required to post their oaths of office at the county clerk and recorder, or at the Secretary of State (district officials). That does not mean that we are limited to that venue. It is still a great venue in my opinion but I have posted by clear packaging tape on streetlamps before the Post Office, Major Church, Library, Clerk and Recorder and Courthouse for ten days too.

I have also used minor legal papers.

I suppose the important question to ask is who is exposed to the notice?
