I find this kind of stuff fascinating.
Just goes to show you that you shouldn't start an argument with someone if you don't know the rules they have to abide by. They might be different than the rules you have to abide by.
Here on TBN many years ago I learned about differences among the different states' fencing laws, trespass laws, etc... when I got into an argument about trespassing. Yes, an argument, VS a discussion. It's very easy to do.
For example, here, it's assumed all land is closed and you need permission to enter it, while in some other states, all land is considered open unless otherwise posted. I did not know that until the argument turned back to a discussion and some links to laws were posted, read, and understood, and then you get that "A ha!" moment that things might not be the same for everyone.
