Q: Is the secured party part of a county or state or is
that something I conjure up?

A: If you use my analogy of the cat scan test - that four
legged animal does not acknowledge a County or State as
that is a man made or mind made concept which does not
exist in any physical reality.

The secured party is you as a human animal, a living
soul if you will, in a live and blood body that walks on
the face of the earth on a particular land mass where
he was born and or presently lives upon.

You don't conjure up anything other than perhaps to
identify yourself as a member of a family grouping that
lives on the continent of NA in a specific location known or 
labelled as Xxxxx.
ie. I am Henry-Frank of the Jones family from Pasadena.
