I see a few others who have hunted for 30+ yrs. have commented on how it used to be more care-free, less "laws", etc... in the "old days". So I must chime in on this point:
I started in the mid 1970s. At that time, I merely went where my mentors and friends went. Eg.: since they took me with them to the old school yards and/or parks, well then .... duh .... that's just where I went. It never occured to them, or me, that there might be anything amiss or wrong. Afterall, they were public parks or schools, so ....... why should we think anything any different?

Of course we had the presence of mind to go at times when the school was not in use, and go at low traffic times at parks, but beyond that, ..... not a care in the world.
Fast forward to the very early 1980s, and by then, our town had a club established. And at that time, the FMDAC had just come out, and was now sending out their monthly periodiocals. Our club joined the organization, so we started to receive these mailers. For the first time, as these newsletters were read out loud at each meeting, we began to hear scary stories of restrictive laws, fines, arrests, hassles, bootings, and so forth. And each issue emplored us to join in solidarity to get parks in far-away places back open, write letters, etc.. And the tone was immistakable: fight now, or this is "coming to a town near you!"
But here's what I distinctly recall seeing in those days, as these new fears began to be read aloud: You could look around the room at the 25 or so people, as these things were read aloud, and their eyes would be as big as silver dollars. You know: "oh my gosh, we're in trouble, what if we get arrested?" and so forth. I mean, keep in mind, that prior to this, it really never occured to any of us that there might be some laws about parks, beaches, school yards, etc.... Now all of the sudden, we were reading actual accounts of (gasp) arrests, tickets, confiscations, and so forth, from far away places (but... of course "coming to a town near you" if you don't act now"). And of course, each issue was packed with admonitions imploring you to know the laws in your area, abide by all laws, ask permission, and so forth. This was also at about the same time that all the manufacturers also became very diligent in printing the "code of ethics" in their sales literature/manuals too.
What happened next though, is something that you could only see if you had been there "before and after": People began to inquire at places they came to, or perhaps even places they ALREADY had been detecting, to make sure it was alright to metal detect. You know, like they interpretted the "know and abide by all laws" as meaning they needed to ask permission or ask powers-that-be if it was alright to detect. Afterall: you wouldn't want to "get arrested" would you? In other words, the scary stories tended to prompt people to double-check, ask city clerks or cops or whatever, lest they be in violation of the code of ethics. An interesting thing started to happen: Places that had simply been detected, and no one had ever cared, all of the sudden started becoming "off-limits". Bootings started occuring where it had simply been an ignored activity in prior years. Old-timers were left scratching their heads.
But ironically, I believe the very ASKING and the very CLARIFYING of all these md'rs, became the very nucleus of WHY this was happening! Because often-time, when these skittish folk appeared at city hall, or county hall, or park dept's kiosks, etc... and started asking (afterall, they don't want to be a stastic, right?) then all of the sudden, you had confused deskbound clerks fielding these "Pressing questions", right? So they go through their rule books, find something they can morph to tell you "no", and presto! No more metal detecting!! I saw this happen at several places just in my part of my state, where no one had ever cared prior to that! And then these same kiosk clerks (who perhaps never gave the matter thought before), guess what happens when they're driving around later, and see another md'r?? They remember the earlier inquiry, and start booting others!
Do you see the self-fulfilling psychology of all this? I know it's hard to imagine now, but for those of you who have been doing this since the 1970s, perhaps you can relate to this. It's as if we were our own worst enemy, eh?
