Use a 7 foot piece of 6" pvc pipe. Dig a hole with post hole diggers about 18" deep. Put pipe in hole....backfill inside and out up to ground level. Grill a 1" hole on opposite sides even with the ground. Paint flat black....looks like a tree stickup. Fill with corn...put lid on. Corn will obviously trickle out....but the deer will learn to paw it...hook it...to make it come out.
