The number increases are due to tracking dogs not corn. With the explosion of tracking dogs, deer that normally would not be found are now, not only found, but reported, because the hunter is afraid trackers will turn them in if they don't report. So one of two conclusions can be made from this. One, the same amout of deer are being killed, just more being reported, or two, if it's the numbers you want to see go down on game check, ban tracking deer with dogs?
