I hunt all the time in ND without permission. And, that's the way the land owner's want it!!!! Before you come down on this, you need to understand the workings of North Dakota.
This law is strongly defended by THE LANDOWNERS. This law gives them the option of either posting it to keep all out or posting it so you have to ask permission to go on. It also gives them the option of letting people on without being pestered.
A prime example happened to me one Sunday years ago. We were in ND hunting pheasants and I'm used to asking permission. So, we spotted a great looking CRP field across from a guy's house. Because we'd have had to park out truck on the road in front of his farm, we went to his door to ask permission.
I knocked on the door and a guy in sweat pants and a t-shirt came to the door. I introduced myself and stated my purpose. That guy came unglued! His rampage went something like this.
"I didn't post my land so idiots like you wouldn't bother me when I was watching football! If you come to our state and are too stupid to understand our laws then you don't deserve to hunt. I don't post my land so I don't have to deal with idiots like you. Just because you are too stupid to hunt without bothering me, I'm now going to refuse you permission to hunt. Get lost."
I kid you not, this is almost exactly how it went except it was laced with words that would show up as "BLEEP" here on PM.
I've never asked again when it's not posted. But, I've talked to several more landowners who felt the same way.
So, make sure you understand another person's rules before you get angry for "trespassing."
