Are there White Oaks in that area? If there are and they had a good mass crop then that is where the deer are right now. White Oak acorns are like Hershey's kisses to whitetail. But even if no white oaks, any of the hardwoods dropping nuts presently is where the deer are hitting. High protein. Keep at it though. If there are deer in that area they will eventually find your hay pile and hit it pretty hard.
