Tom it may not be in your state? But in some states ....
itsaring, you go on to list dire-things you've heard of (sharks teeth, lawyers, etc...). I'm going to go out on a limb here and suggest the following about your examples:
1) In each and every case, was the location and activity (md'ing or teeth-collecting) something that COULD have been looked up ? And as such, the person WOULD HAVE seen the rule (Eg.: "no md'ing"). Right ?
If so, then presto : This does not equate to "md'rs should grovel wherever they go". Lest, gasp, jail await them. Instead we/they can merely look up rules and laws (in this wonderful digital age we live in). And if it doesn't say "no md'ing", then : Not disallowed. And ...no jail, no lawyers, no fines, etc..... And all that was accomplished without the need to swat hornet's nests.
2) But if I'm wrong, and the "dire examples" you cite were at mundane benign locations, where there was no specific rule (and they were roughed up for "disturbing/altering" or "harvest/collecting"), then here's what I have to say about that :
There will ALWAYS be fluke examples of over-zealous cops, that take-someone to the cleaners for something as silly as jay-walking , etc.... I mean for example : I have a newspaper clipping of a guy that got a ticket for eating a hamburger while driving (I think the cop called it "distracted driving"). And I'm sure if we scour the newspaper headlines long enough, we can find stories of persons "roughed up" (tickets, jail, confiscations) for nothing but a tail-light out. SURE ! But notice that none of us fears driving. Why ? Because we recognize such stories as "flukes"
I'm not saying to "throw caution to the wind". My aim is more that : The solution to any such "dire stories" is NOT to run around seeking express blessings, sanctions, permissions, etc... (where there was never specific rule in the first place). Because then sure as heck, someone's gonna answer the "pressing question" with a "no". Or invent a rule to address the pressing-issue.
3) And regarding the "flukes" potential above ^^ If and when some individual rangers DO "rough up" and focus all their time and energy on "this evil activity" (at some place that might have SEEMED benign), then : I have a sneaking suspicion of what caused that individual ranger to be so up-in-arms zealous about our particular activity.
Care to take a guess ? And no, it was not "holes". And no, it was not archie concerns.
