.... I had read it in newspaper article
Maybe I'm confused on what you're saying. You read *
what* in a newspaper article ? That someone was detecting private land, with permission, and STILL got his chops busted ? Or was detecting public land, where no prohibitions existed, and still got his chops busted ? Can you clarify what "
it" is ?
.... " You need to be have writing permission with you or something that clearly states that it is public property when every they are out at that area" ....
Why does someone need to have permission , in writing, when detecting on public land ? Assuming, for sake of discussion, that md'ing is not prohibited. And if you have any story where someone got his chops busted for detecting public land, where not prohibited, I would very much like to see it. I have a suspicion that something
else was amiss. Ie.: someone being obnoxious in some way. Or someone sneaking an obvious sensitive monument. Or someone who cant' take a warning (because perhaps someone thought he was about to leave holes) etc...
I have no doubt that "newspaper clippings" can be found, where, sure : Someone got his chops busted for md'ing an inncous sandbox @ a city park where no rules existed. Sure. Flukes happen.
So too can I show you a newspaper clipping where a guy got a ticket for eating a hamburger while driving . (No joke !) Obviously such a clipping is a fluke by an over-zealous cop (he called it "distracted driving"). And obviously no one is going to stop driving when they read such an article. And obviously we don't go seeking permission to eat hamburgers and drive now. And obviously we write such flukes off, for exactly what they are : "Flukes".
Unless I'm mis-understanding what you say we need written permission for. Because unless there is some sort of specific/explicit dis-allowance of md'ing on public land, then .... no ... No permission is needed . And same for private land. If someone says "go ahead", then verbal is fine. In the same way that if you invite a guest to your house for a party, they don't need to "carry around written permission" while in-your-house.
