Don't suppose that hunting over a water hole is "fair" in your eyes either, huh? Such as lots of bow hunters do for antelope. Don't suppose you like mtn. lion being tree'd either? Even though it gives the hunter a lot of time to determine sex of the cat and weather or not to shoot it or let it live another day. Much like a hunter can do while bear hunting over bate. Gives the hunter a lot of time to determine sex of the bear and if the bear is a of size that the hunter is looking for.
You probably don't sit over a well used deer trail either. Why, after all, it's just not fair knowing that the deer use the trail often and there's a good chance that they will come down that trail at any moment. How fair is it to sit in a treestand 20' up out of the deers view and getting your scent away from them. Almost like cheating isn't it!
By the way, I've never bear hunted, not even over bait. BUT at least I understand the vailidity of it!!
