400-700 ears of corn??? That is a LOT of corn! Even when we had kids at home, we wouldn't have gone through that much in 2 or 3 years! I have to say, tho, if you're eating that much corn, you need to make sure it's not GMO. If you read up on GMO corn, it's a little scary. I even started buying non-GMO pop corn and then corn starch, since I'm using it in place of flour for thickening, etc.
