Keep the setup as is for now, but keep in mind that the corn is now mature and deer will be hitting it. I hunted a similar situation where the fields were about a mile from where I hunted. I found an area that was being traveled by the deer on their way back from the fields and setup there in deer season. Long story short we shot many deer over time along that travel corridor. Are there hardwoods producing acorns in your area? If so they will be dropping now and that is another food source that may change the deer's feeding habits.
