Well, personally there is no such thing as a magical product for deer .

But also, like acorn rage. If there are no acorns in the areas you hunt. Using this product would not be worth using.

DeerCain, will work only if they find it. Same with apple blocks and licks or other flavors.

Food plots are pretty good to use if you can plant in the area your hunting.
We all know you got to till up the ground. But if you cant do that. Just try throwing seeds that will grow and you still get some plot to grow.
