I got my first deer in a similiar situation. I have 3 of my 9 acres in woods, wedged between approx. 200 acres of corn. I found the deer trails, dropped some salt blocks to 'train' the deer, and then set up my treestadn just off the trail.
I actually got my deer the day they were harvesting. I saw him enter the cornfield about 35 yards from me, then the combine came by and scared him right past my stand:-)
So, consider being in the stand the day the harvest if you are still hunting then.
One more nice thing is that the corn will protect the deer from gun hunters until it is harvested.
