That landowner story has been making the rounds for years and most landowners will tell it. Insert two Texans, or WI. I have heard it many times. Think about it, if cover is so thick you can't see what you are shooting at, how is a bullet going to make it through the cover to kill a moose? I know wardens who chuckle at that story and it has been spun on everything from horses to llamas. It's like the story I heard as a kid, a Montana kid and a ND kid were standing across from each other on the state line. The ND kid was throwing fire crackers at the Montana kid, so the Montana kid lite them and threw them back.
Here is my take, modern hunters are accustomed to hunters having to wear orange and assuming if it's not wearing orange it probably something to shoot. Now take away the orange law and you actually have to make sure of what you are shooting at. Like needing seatbelt laws we need .gov to make us safe.
