I have had several natural blinds kicked apart over the last few years, when guys come and put tree stands near them. Some think that if they put a tree stand in by your blind that they have superior authority and can kick you out. It happened again just yesterday. I was told that it did not matter if he was there or not, he had cameras and would know if we hunted around any of his six stands. I straightened him out about unearned authority and Iowa public land usage. If possible construct natural blinds where no one would ever want to put in a tree stand.
