They will most likely be moving during the dark. Your best chance would be to get out early, before sun up, and out early around 5:00 and stay till you just can see. Take some post hole diggers and dig you a couple of holes in a location that you have been seeing wallows, ruts, and tracks. Dig a couple of holest as deep as you can in this location. Fill them half way with corn (soured or just plain corn, either works just as well). pour a pack of dry jello, in the hole and then fill it the rest of the way with corn. Do this to all the holes. Go back and pour another thing of jello on top of the holes to entice them. Do this at least 5 days before you plan on hunting. They will find it and dig at the holes for about a week. Once they find it, they will come back every night until there is no corn or smell of jello left. You will be surprised how big of a wallow they will make out of each hole. This is the easiest way I have found to bait them in a quick situation. Best is to make a feeder pipe/ barrel. Some times the present of a pipe or barrel will throw them off for a week or so. So the bait hole would be the best bet for your situation.

You can also use molassis in place of the jello. I sometimes use them both. One hole with corn and jello (strawberry is the best) and another hole with corn and molassis. Put out as many holes you want. The more the better. Also consider your cover when making hole placements. Want to make sure you can make a good shot.

Hope this is what you were looking for.
