Like you, I have more experience in one type of hunting, but for me it's all famrland....with corn, beans, alfalfa, etc. I have dealt with the corn in several ways. What is right for you depends on your situation.
1. I ALWAYS keep one stand ready to be set up (or a climber, if you are inclined). I use ladder stands, but always have one bolted together ready to be thrown up on a moments notice. Many times you'll get into your location and notice a key insight that clues you in to a better ambush site (like seeing deer take a path fifty or sixty yards away). Some will move that stand, but I prefer to add the ready-to-go one for time saving, less scent intrusion, and I can return to it for a lilttle scouting if need be to better educate myself.
2. Edges...obvious key. No real need to explain.
3. Look for partial cuts. Deer will follow the cut corn. I almost always see the highest deer count on stand during the season when I set up on the edge of a fresh partial-cut section of corn (Ie a corner of a field when the farmer ran out of daylight, etc.). Sometimes the farmer will cut an inside section that allows deer to feed out of view from roads and other open areas. I had one last year not 50 yards from my house that the farmer went in and cut a 30' x 80 or 90' section for whatever reason. You wouldn't know it was there unless you explore the tractor's swath (path). It was there for about a week and you couldn't see it from the house. I had a daily average of 29 deer (some were repeats) sighted on evening sits.
4. No cuts...look for hedgerows or thin strips of timeber connecting fields. While deer will be fat and happy in the corn, they'll freely use the hedgerows for travel, and sometimes you can find a path being taken from field to field. It won't give you much notice as to when they arrive, pass, and disappear into the next field, but you will have a good amount of activity. Oftentimes, these trails crossing a hedgerow will have a scrape or rub. While I do not hunt scrapes too often (too much nighttime activity), scrapes found at these crossings are good indicators and often have a higher daytime usage by bucks since they generally feel more protected and less vulnerable due to the standing corn. They're usually on the outside edge of the hedge row and in a section where the corn is a few feet from the hedge row (like where the tractor goes around a puddle or muddy spot and it spaces a few feet between the hedge row and corn). I also prefer this to an evening stand often due to increased activity and easier to enter/leave.
5. Stalks can work, although I prefer to no do this except on windy days where I do not want to be in a stand. In this case, I often set up a blind in the corn itself, or stalk lightly. Very interesting hunt style and can be worth the gamble at times. I usually get to the wind-right side or corner of a field and work my way up the rows.
6. Try to find open areas to glass from afar before the season. I'd go there and sit for three nights in a row to find movement. Use that as a starting point for scouting...Once you locate some movement (doe or buck) and nail their entry/exit points down from the open area...I'd risk a one-time scent controlled scouting mission. You'd be surprised what you can get nailed down in this manner. Do it about 10 days before the season...find your stand spots, get them set, and get out. you should find that path will lead at some point into or out of the corn. There's your starting spot. They're using it for a reason. You may find that spot is perfect for a stand. Or, you may put one up and quickly find out why they're using that path. Whatever the case, they're using it for a reason, because they'll be patternable on a semi-regulr basis during the early season. I once found a doe trail from afar, went in, set up a stand on a hedge row...sat the first night and found the bucks were using a trail about twenty yards up (no shots available from the stand). I set up my ready-to-go stand the next midday. Hunted it the following afternoon and tagged on a nice buck. Like I said, you'll find your keys this way.
