I went through the same thing one year. I am all set up on private property. Owned by a co worker. I am all jacked up for this hunt. I am sitting in my tree and hear walking. Oh here comes my deer. Turn my head and see a walker in orange. IHe has no clue I am there. As he walks under me I ask what the hell he is doing? He is surprised I am there. He says he has permission. I say the ..... you do. Yes, we have been dogging this property for years now. I ask to see written permission. Dont have that he says. I reach in my pocket and say I do. Turns out they had permission from the owners past father 20 years ago. The son came and told them dont let me catch you guys on here again.
Here is the funny part. The next year I am in the same stand and hear the same sound from the same direction as the year prior. I was no ,,,, way, not again. Turn my head and it,s a buck. That was the best sight to see. Well next to him dropping 20 yards after I blasted him. LOL
