Well, I would say, if you are almost positive the does are spending their time in the corn during the day, set up a stand along a field edge to maybe a shot at a buck harassing one of the ladies in the field or on his way out of the field. Another option is setting up on the inside edge of a field corner. Hang a stand a few yards in from the field edge, preferably one with something that funnels them through that narrow inside corner, and try to find a tree that allows you to see in all directions fairly well. That way you can watch the field a bit for the does you suspect to be bedding down there, and your're also able to hunt a pinch point where bucks may have to move in search of said does. Obviously this is all hypothetical, but its a thought, Maybe try posting up a pic of the property(ies) and we look over it and offer more suggestions.
