I'm not sure I'd like hunting the edge of the yard. But if he wants you to thats his think. If he's ok with you hunting the rest of the property I would hang other stands as well. If I hung one near the yard it would be in the woods some not directly on the yard. Eight acres doesn't seem like alot but if the habitat around is good the small plots like that can produce some nice deer. Check out my Avatar. That buck was shot on 12 acres and there sure isn't 8 total acres of woods on that property. The surounding area is good though. Bigger lots mostly.

So do whatever he allows but don't expect the small area to be a totaly easy hunt. Scout the woods and figure out better what the deer are doing and then go after them. They may be in the yard but hang up 30 yards in the woods for a while before comming out... I see the yard no different than a food plot. After all thats why they go to the yard.
