Old school hunters (age anyway) are the ones that usually walk in on me that I have the most trouble with because since they been hunting that piece of land for 40+ years no one else should hunt it. As I see it public land is public and it's like fishing don't move in on someone and if you do back out and go deeper in the woods. As far as people getting shot that's the fault of a unethical hunter not being sure of his target and pulling the trigger anyways. Be sure of your target and hunt on.
