"It worked for me in the one instance I tried it (Park District Superintendent) ...."
This simply means the person you asked, did not have the right mental images, full picture, etc..... How much you wanna make a bet, that I can just as quickly get your "yes" revoked? All I'd need to do is go to that same official, and ask why Dan was allowed "dig" in the park, and keep "city valuables" for his own mantle-place? And what if he found an indian artifact and the city got sued over it? And so on, and so forth.
There are bound to be cases of people getting yes's (like yours). And what that tends to subconsciously do for people, is simply reinforce that they needed to ask. Ie.: the "yes" or the "no" they got, to them, simply means that this is proof that permission was needed. Because otherwise, the person they were asking, would have said something like "That's silly. why are you asking me?", etc... right? But this does not logically follow. Most bureaucrats, cops, etc... will be happy to grant you their authority, or deny you, when you grovel with questions. Afterall, you asked didn't you? Thus they too must be thinking "I guess this is a question that needs sanction". So I do not look at "yes's" or "no's" as reasons why others should assume that permission for places where it's not disallowed, is therefore necessary.
And for every example someone can give of a "yes" they got, I can give examples of people who got "no's", at places where no one was ever bothered before (and where it never occured to old-timers that there was a problem, as no one ever had a problem). But lo and behold, someone takes it upon themselves to walk into city hall, and they get a "no"? What's up with that?? This happened in my town. All we could figure was this newbie got a deskbound bureaucrat, who morphed something odd to apply to his question? And odds are, even whomever he talked to, would probably have never given the matter a moment's thought, until this "pressing question" crosses their desk. Much too risky. I can give example after example of this type thing happening.
Even on a state-wide basis it has happened: The state of Utah, who apparently used to have nothing on the subject in their state park rules (unless you tried hard to morph something about cultural heritage, or disturbing the vegetation, etc...) one day issued a addendum or clarification to address the issue of detecting. They go on and on with dire sounding things (not unlike other state's state-level parks have). But the interesting thing was the introductory paragraph leading into this dept. memo. clarification: It said something to the effect of "...
Due to numerous inquiries the state park's dept. receives each year, this will serve to clarify .... blah blah blah" You
see Dan? Apparently up till then, it was a grey area (as long as you weren't a nuisance of some sort?) But given enough "inquiries", what do you THINK the safe answer will be? Sheesk, this is a perfect example of the self-fulfilling cycle we put our own selves in.
As for "contracts", I used the word loosely for having someone sign something. I suppose that's an innacurate use of the word
