You should be ashamed of yourself for not looking in the cornfield. I know from experience that a heart shot deer can go at least 200 yards without any blood on the ground except for the initial hit. If you rip the ole blood pumper apart theres nothing left to pump the blood out of the hole. Thats why you should go for the lungs, they will leave a lot better trail. But if you knrw it went into the corn you are one lazy person to not go looking.
