Interestingly all your cogent objections and not so cogent suppositions are already addressed in the link to the actual Florida law I provided.
No, they are not.
Logic would not dictate that private roads lead to inevitable public roads.
Yes, it would. If there were no public roads, there would be no private roads. It would just be roads, which are defined (per your link) as
[FONT="]“Road” means a way open to travel by the public...[/FONT]
I'm not a lawyer, but that sounds like a public road to me, even if they don't dumb it down to "this is a public road" or something like that. It is open to the public. A private road is not. There may be some Florida weirdness saying that because my driveway links to a way open to travel by the public, my private property is now also open to travel by the public, but I doubt that.
Florida recognizes several different types of roads, many of them available for the public to travel on, but they do not define anything identified as a "public road".
Because the legal term "public road" does not seem to exist in Florida, does that invalidate the concept? If I were involved in a court case and used the term "public road," might a judge understand what I was talking about? What would he or she think that it meant? Would this be relevant in a courtroom?
The point I'm making here is that this is a forum reserved for dealing with legal issues. I've provided you with the law. You have replied with assumptions and ideas that are not found in the law. Statements like "is there a law saying that I can't", "There is certainly an implication that the public owns public roads", "If it's a county or municipal road, there may be other laws in effect" will get you a grin and maybe even a little laugh in court but they have no legal merit.
If anyone wound up in a courtroom over this, I apologize. If they did not, I'll enjoy a grin and a little laugh myself.
Read the link and give up on the silly assumption that if the law doesn't say you can't blow up bridges, poison water supplies, paint children organic green or kick weasels then it must be legal to do those things.
If it's not against the law, then it's not against the law. Are those things not against the law in Florida?
And yes, if it's not against the law to do it, then it is not against the law to do it. That's the way the law works, as I understand it. Again, not a lawyer, but if I went and blew up a bridge and there was no prohibition against manufacturing an explosive large enough to do that (there is), and no prohibitions against impeding traffic or damaging public infrastructure (there are), and I was allowed to be there (I am), I'm not sure what they would charge me with.
I specifically quoted the part of the Florida law that limits what you can do with a publicly accessible road. The word “Road” in Florida means a way open to travel by the public. Travel is your right when the road is open to the public. You have no other rights to roads. Read through that law and see for yourself.
Honestly, I have better things to do with my time. Can you point me to something that says that the OP cannot do what they wanted to do?
Outside of the law question you may be free of arrest during your digging of public roads. You may remain undiscovered much like many crimes go undiscovered. You may be given a free pass by local officials who don't wish to enforce the laws already on the books, that happens all the time. You may exceed the speed limit like 40% of all drivers and never get a ticket but that doesn't mean if you aren't caught that it's "legal".
Did you know that there's no federal law prohibiting the possession of a flamethrower? I'm not talking about that Tesla toy, but rather a military grade, torch-a-bunker flamethrower with the fuel tanks and ignition flares and all of that. I only learned that about a year ago. There may be some local restrictions, but federal law does not prohibit it because federal law does not prohibit it, meaning that it's legal. It's a mind blower, but there we are. That's exactly how I can legally metal detect in local parks and on municipal property - because they don't explicitly disallow it anywhere. I'm sure that if I asked enough people, I'd eventually find someone that would tell me that I couldn't. But I don't ask, and the existing laws don't prohibit it, and there I am.
Am I misunderstanding how citizens can purchase flamethrowers, and how I metal detect on city ("public") property?
To answer your question "is there a law saying that I can't?" Yes, even the trespass laws are clear enough to get a conviction. I'm pretty sure the construction area was marked off with cones, tapes or signs and there is a sign warning "Road Closed". In the law that's considered enclosed and posted.
OP didn't make it sound that way. If there were fences, or even signs, I would have advised otherwise. It didn't sound like that to me.
I don't have a dog in this fight. The last time that I was in Florida, barring airports only, was over 20 years ago. I believe that I gave good advice. If you would like for me to say that I gave bad advice, I'm willing to do so if it will make you feel better. I don't think that I did though.
No balls here (girl) maybe that helps! Haha. Went and detected it today, unfortunately they already put a layer of new dirt on there when i spotted it so i didn't get there soon enough. All I found was this thick piece of glass that looks kinda old but I'm no expert. It has seams and is iridescent, flakes off so maybe not. Other than that just junk and melted lead.
Were you arrested and/or fined during your search? Asking for a friend.
