I am fairly new to hunting, but have access to some private land here in Knox County Ohio. I had been hunting and decided to lay out a bag of some Magnum Buck Corn mix on the edge of a field to see how fast it would get eaten. I let it sit for about a week and I came back to it today to see over 3 large rubs on the trees on the edge of the field very close to the corn. Do you think this is a sign made by a buck saying "this is my food, stay away"? Is this a place I should be watching and even putting up a small feeder at? Not all of the corn is gone yet, but I was told he might be trying to "protect" his food in a sense. Any help or advice would be much appreciated. Thanks.
