Just like everything else in life...(with the exception of Politics) There is an ethics to it if you look close enough.
In Hunting, it is the 'Fair" chase.
Part of the fair chase on deer is you can not bait them. In other words, you can't set out say a large pile of corn and then ambush them when the deer come to it.
Years ago when you were hunting for Food, this was acceptable and even one of the few way to ensure you would have meat to eat.
My dad was part of the old ways for years, although he finally changed about 15 years ago.
Now when dad feeds the deer he puts out this sign....
I guess this may cover him!
