If you have any nut producing trees, you won't need corn. One thing I would look for is deer poop, and a LOT OF IT! If you have acorn trees with lots of deer poop around, set up around this keeping the dominant wind in mind.
Then, find a spot along the field edge. This will make a good evening hunt.
If you don't have any oaks, just start hand corning places. If there are deer there, they will find it pretty quick.
