What are the rules or ethical concerns about using another guy's blind? I recently went for a late-season weekday hunt in an unfamiliar area (public property) and found a nice blind that was unoccupied. It was just after sunrise so I figured the owner wasn't going to show up so I set up operations and had a very "producktive" day. Was I wrong to do this? If a guy sets up a blind does that mean he has exclusive rights to that area? Your thoughts please.
