You cannot hunt over bait, and you are in violation of this rule even if you don't know the area is baited. So, if you know your neighbor is baiting don't go within shooting distance of his property line. It is a violation to place bait in such a manner as to cause someone else to unknowingly hunt near it. So both you and your neghbor could get in trouble. I would call my local agent if I were you and ask him to fill you in so you can hunt legal. I will begin feeding deer too after muzz season and after all the bowhunters have indicated that they are through. It really seems to pay off to attract deer over the winter and keep them healthy and well fed until 10 days before someone wants to hunt next bow season.
