Loco-digger, I enjoy your posts very much. Not to hijack the thread here , but I have a question on this "according to their rules" : In the particular places where you think that exists, have you ever actually looked to see if it's really written there? Ie.: a chapter and verse that actually says that ?
Because there's been answers that come back, when persons, decades ago, went to compile lists. Where .... yes ... they got various entities saying "with permission". Or "at the discretion of .. " type effects. Yet if you look closely, the text saying such things is usually not accompanied with any sort of rule that actually said that (to our hobby, anymore so than any other hobby). Instead it appears to be someone answering an inquiry to a someone in the past.
We have something like that for CA state parks, for example (if the FMDAC state by state listing is to be believed). But when you go to click on the supporting links to actual chapter and verse, you see no such thing requiring that. So I am led to believe it's just commentary. Or ... kind of like : They could tell you to stop, if they wanted . Ie.: they have discretion to decide something isn't safe, or is harmful, or annoying another camper, etc.... Sure. But did that mean you had ask ahead of time ? No.
Someone, ages ago, answering an inquiry, was just pointing to the fact of ranger's discretion. But as time went on , md'rs (and the lists they compile) got morphed to think it meant "must get permit" or "permission" etc....
