Unintended Results
I don't bait, but understand why in a place like West Texas. Let the state game agency decide. They are in charge of protecting the game throughout the state and not in just one square mile.
Baited areas can attract hunters over and over. And that can lead to deer scenting the area, leading to less deer visiting in daylight hours or at all.
I don't see it as a question of ethics. I just don't like the idea of hauling a forty pound bag of corn, a half a mile into the woods. That's the kind of hard work I know deer will surely scent.
