Just remembered that on a Minnesota-focused hunting and fishing site last yeara guy posted a picture of his "corn stand." It's basically a six foot tall step ladder he modified with a seat on the top and foot pad near the top so he could sit just above the corn with enough room to draw and aim at the deer through openings in the corn (after breaking a few tops off. He set it up far in the corn near travel paths and also just a few rows in near water sources and fencelines, etc.
