What I do when hunting near a cornfield if I'm the only 1 allowed there is to pay the person for the corn at going rate they sell by bushel to leave a couple strips unharvested so it'll be there all winter drawing them. The fact they are busting you on entrance or exit you'll have to move stand almost daily, and/or have a buddy decoy himself to distract them while you get in stand, and/or make a WIDE loop, and/or have a buddy walk with you and when you drop off, he keeps walking.
