K-in-TN, aside from the "locker-room" talk, you will see that what I am MOST HARPING ON, is the ORIGIN of such laws. And I am convinced that most of them, got on the plate-of-thought by powers-that-be, d/t skittish md'rs waltzing in and swatting hornet's nests. Thus rules/laws born "to address the pressing issue" on their plate.
So I can see how you would see how the notion of "not asking" (and , instead, looking-it-up for oneself), might SEEM like promoting lawlessness. And yes, I confess to locker room talk BTW.
But you will also see that I have repeatedly said that, once a law exists, then .... by all means, obey the laws. But am just trying to point out that it is often we md'rs ourselves, that brought these upon ourselves. And encouraging people to look up the laws/rules for themselves, be-low-profile (so as not to elicit busy-body lookie-lous), etc.... That is not the same as encouraging people to break laws. It's more along the lines of encouraging people to look up for themselves. And to recognize how those laws, that they lament, got started in the first place.
(but yes, I confess to locker room talk on occasion).
I may have an answer for you on when the law was enacted but I might wrong as well...
When I was young people were allowed on these beaches they used to give dune buggy rides for the tourists which I was one of... then they stopped allowing as it was destroying bird habitat as well as the dunes... water Walker might be able to verify this or not.
