Policy to not notify
I have also been curious about those kind of laws. A couple of months ago, I came way too close to being slapped with a $1000 fine for being in the wrong place. I always assumed that if someone doesn't want you to go somewhere and will fine you lots of money if you do, there would be a sign involved. I was on private property with the permission of the owner, and I was following trails on the property because it's just courtious to the owner. As I was leaving the property a policeman (who was very civil and nice about it) informed me that from the nearby road he could see me and I had apparently crossed into state protected land. I never left what was obviously a well-traveled trail, and didn't cross through any fences of any kind. The policeman said he would refer me to the BLM or Forest Service (I can't remember which to be honest, I am not knowledgeable of such things), and they would decide what to do, if they wanted to worry about it. Well about three months later they contacted me and said that I was in violation and they needed me and my buddy who was with me in an S-10 to come and get our $1000 fines right away. I demanded an explanation and I was told that apparently a while back they made a law stating that the BLM doesn't have to post signs warning when you are crossing into forbidden territory, that it is the driver's responsibility to check before-hand. I found that ridiculous, the implication that I had to check with authorities about every possibility before I do anything. That sounds a lot like how governments in other less freedom-loving countries do things, which I have personally experienced. The fact that they would give me a $1000 ticket for the first time being 100 ft on the wrong side of an unmarked line was absurd to me. Both my buddy and I are Air Force, and luckily he had already left, PCSed to Alabama, so the guy let us off since he couldn't get both of us for the ticket and it wouldn't be fair to only give it to one of us. Now I'm afraid to leave the road because what if I cross that invisible line again? I can't spontaneously off-road on obvious trails anymore. I have to track down the local office, go there during business hours and ask permission or more information for every area that I go to. Is there a better way to know where I can and can't go? If I see a trail, how can I know if I'm actually allowed to be on it if there is no sign or anything?
