Anybody ever did side by side comparison between Buck forage Oats and the regular oats you get at the elevator or feed store? I dont really care about deer presference as much as I wonder about cold tolerance. My hunting land is in the Upper Penninsual of Michigan so zone 4. If there is some evidence that they stay green a few weeks later into the season then that might justify the cost. If you have any experience with this product would love to hear it.
