I hunt public land exclusively. You made the right call. I often had other hunters coming in in the dark and if I was already in my stand I would hit them with my flashlight and let them know where I was. Most move to a different location and if the tables are turned I have to be the one to relocate. Its only hunter ethics 101. But sometimes you have a slob hunter that will deliberately park his butt right by you. That's when I go tell him to please move to another spot. If he refuses I notify him that he will not see any deer there because I will make his sit a waste of time. I might just have to take a dump right behind a tree by him and whistle while doing so...lol
