Lets say you had access to 100 acres of corn......and the deer were using only one trail to access it. You hunt that trail every day.

Ya think they "might" change up their pattern?

Difference in hunting ag fields and baiting is the size of the "pile". So let's say you have a man "baiting" who sets up multiple bait sites (increasing the size of his "pile"). He hunts only the bait site that he can access playing the wind....never hunting a bad wind....and never over-hunting a spot. That guy is upping his odds. I dont' know ANYONE who does this, personally. But that doesn't mean it couldn't be done with precision.

Most people who actally bait are as dumb and lazy (the people I know who do it) as you give them credit for. Their results reflect this. That's why I profess that it isn't an advantage for the "average" guy baiting.
