Lots of waterfowl guys get nabbed for shooting over flooded fields that were baited by an outfitter. You can't tell from looking, and likely the hunters had no knowledge, but the law requires you to know, and guilt is based upon the appearance of guilt, i.e.you were there, you were shooting, therefore you are guilty, whether you atually participated in the baiting or not. I believe it is true,or at least used to be that, there was a 10 day withdrawal period, after which the field was not considered to be baited. what! On the other hand you could plant a crop, leave it stand, flood it, and your legal, or cut and flood and it's o.k. Dove outfitters in the south spread rock salt, easy to get nabbed in that deal too!
