Well I technically don't own property, but I will inherit it. I don't see anything wrong with that. Yeah, if someone shot a deer and it ran onto my property, go for it. Heck I'll even help you track it. All I'd ask is that you'd let me know. What would happen if you found a person or persons on your property without permission? "Well I'm tracking a deer that I shot." You wouldn't know if that person would be telling the truth or not.
