You said you knew the date they harvested the corn every year. Which is great. I assumed you knew that to be after your plants would be done. Corn that is grown for animal consumption is harvested in October, unless you have real early or real late plants that is when your plants will be done also. The trick is knowing exactly when they are going to harvest so you can get your plants out ahead of them. Sounded to me like you have that part covered.
Corn that is grown for human consumption is a very small percentage of all the corn grown. It is only about 5 feet tall and is harvested much earlier, as opposed to 10 foot and more for feed corn harvested in Oct., so now you know what kind of corn you have. I doubt that its sweet corn.
Don't listen to the naysayers. It can and has been done. Do a search on it, there are some documented cornfield grows.
Where I live lots of people plant in cornfields so the rippers walk the cornfields and LEO flies over them. But you can still get away with a few plants here and there if you do it right.
Good luck with your grow, you won't be sorry you picked a cornfield to grow in. Tell no one and leave no trail or trash.
