Chaos55 -- I did talk to the guys behind the counter 'at the license office' and they said 'yes' when I was purchasing my permit. As for Lake Pleasant, that day pass is only needed if you stop inside any of the develpoed areas, including a toilet stop.
The office guys were kind enough to let me behind the counter - so to speak- to show me what to look for for signage for the various types of land. I left with the idea that any white sign means you need a permit; and teh official language in the law states
"State Trust Land requiring a permit may or may not be posted..." which pretty much says it is a damned good idea to have a State Lands permit whenever/whereven you drive inside Arizona.
Good luck on getting a meaningful answer from them, take names and badge numbers, but we shiould all remember the written law overrules whatever they tell you.
These statutes suggest the owner currently cited for trespass doesn't meet the statuatory description for tresspass (37-0501.1). Below are two main statutes I could find relating to use and premits. It's worrisome that with 37-1153.A and D the agency can create rules ad-hoc and they become legal requirements; such as "even if not properly signed" you are still guilty of trespass. Should be an easy win in court, but bothers the heck out of me when any public agency is given that level of latitude.
