Me and my wife are having the exact same problem. Used to we would see at least 2 or 3 every time we went. Now if you see anything at all you got lucky. I been getting pictures of a pack of dogs running around since August and they ran through my wifes food plot with her sitting there. I don't know what's going on with the deer this year but in my opinion between the dogs running around and still having acorns on the ground in January can't be helping the matter any.
