Good-guy, I don't know what to do on a national scale, but on a one-on-one personal scale, (peer to peer, friend-to-friend), I encourage keeping a low profile, avoiding sticking out, etc.... NOT BECAUSE ANYTHING IS WRONG WITH IT, but because, with our odd-looking space-gadgets, we tend to draw stares, attention, etc.. from busy-bodies.
If it were just a random guy here or there, in a certain park green, 1 or 2x per month, no one would care, right? But if
10 people go, for
10 days straight, busy-bodies will watch and say "Just
what are they doing anyhow?" "Is it a club?" blah blah. Do you see how a single person, who acted like he "knew what he was doing" went un-noticed, and no one thought to spoil his fun? But when 10 people do it, all looking over their shoulder, PRESTO, people wonder if you should really be there doing that. Just like nose-picking: if you are discreet, no one notices. But if you and 10 buddies do it at high noon at Main and 3rd street, the city clerk will tell you that you need a parade permit.
So on a one-on-one basis, I can get people over this hurdle. But on a national level, I wish I had a better idea.
I recall, as a 19 yr. old kid, that another 19 yr. old I hung around with, bragged that he could get into any bar, anywhere in town (CA's legal drinking age is 21). I asked him "wow, I guess you have a fake ID, right?". He said "no, no fake ID. It's easy: you just 'walk right in like you own the place', and no one cards you". He had figured out that it's only those that stop at the door, look at the bouncer funny, try to avoid his scrutiny, etc... that get carded. If you just walk right in, not even thinking about it, people assume you know what you're doing. So....... yes I know this illistration is "strained", because in that case, the kid is breaking an age law. But the psychological point has always stuck out to me, that sometimes, "no one cares or notices, till you ask". I think this psychology is very strong in our (md'ing) case, when there's really nothing specific to disallow md'ing in your locale.
Now, how to convey this on a national scale? Probably impossible, because it's an "attitude" and a "psychology" that can not be put in to print. People tend to want the park to have a blazing sign posted "metal detecting IS allowed, come one, come all!" lest they risk "getting in trouble". Unfortunately, we're in a hobby where ....... just like fishing ....... 1 or 2 guys at a secret fishing hole is just fine. But when 20 people want to descend on that same fishing hole at the same time, a) there's not enough fish to go around, and b) 2 out of those 20 will run off to their nearest bureaucrat wanting rules and laws to be enacted to maintain order and legality on the fishing hole. c) meanwhile, those first one or two fishermen who never had a problem, are left scratching their heads thinking "what happened?"
