Tommy, I'm not sure the policy on abbreviations covers whether or not add "County" or "State" to the name of various counties and states.
For example, it says not to use "R.I." for Rhode Island, but not whether "State of Rhode Island and Providence Plantations" is allowed. Less ridiculously, it's also silent on whether we should use "New York" or "New York State"; or "Anaheim, Orange County, California" vs "Anaheim, Orange, California".
