So if my three year old accidentally wondered on to your property, then I need to call you to come get him? It's still trespassing if I don't, right? According to many people it would be and they would have me call the landowner while the child sobs and wanders around aimlessly, stepping into briar patches and the like.

In Minnesota, you can legally retrieve a dog that wandered onto someone's property without asking if you lay your weapon down first and then walk in. You have to leave as soon as you get your dog.

So even government sees this isn't such a black and white issue

I get the point. It's your property. You own it. You have all the legal rights associated with it. But the it's mine and stay the hell off it under all circumstances unless I issue a formal ruling dictating you can walk a few feet over the line for a few seconds is more than I could stand to live with. If I know someone has that mentality, I steer very clear of any land around them. But thankfully, most of my neighors have the same mindset and we'll continue to allow each other to retrieve deer, dogs, children, etc. off each others' land without calling everybody first.
