RE: big buck tactics
If baiting is legal then I would suggest that you do that now. Moultrie has feeders for $20 that the deer bump to get corn. This way it keeps rodents and other species from eating through all your corn. Leave the buck alone for at least a month and let him become comfortable with the feeder before hunting him.
I would then place a stand on the trail that leads to the corn. Don't directly hunt over the corn. Also, try and stay as scent free as possible. Don't go in there with the idea that you are going to throw up a stand and kill him in a few seconds, deer aren't dumb.
