Here in southern Iowa I can tell you that hunting corn fields just after they have been harvested is a real good way of getting close to a lot of deer. I' ve seen cornfields picked in the morning and have 30 deer in them by the afternoon. Deer love to gleen the corn after it' s been picked. But if the farmer brings in his cows to gleen it after he' s picked it, the deer won' t go in there. They will move off to a different spot. Hope this helps.
