There are many ways to attract deer. Foremost is food source. Just a corn pile by itself is not very effective. Feeders are considerably more effective however, just putting feed out will not hold deer. That requires habitat manipulation and that is far to deep a subject to deal with here.
I agree.... I only bait to see what has made it through the deer hunting season and to find out how the overall herd is doing (body size).
I also bait to see when bucks have dropped their antlers. This way I know when to begin shed hunting- one of my favorite pastimes. I do however use mineral lick sites to help the deer with their mineral needs and nutrition.
