It's too bad you can't make a rub line and add it into the mock scrape mix, or can you? Yes, it takes a bit of sweat equity, but you can build a rub line. First, you need to consider what trees whitetail like to rub on the most. Studies have been done on this phenomena and it clearly shows that the more aromatic the tree, the higher likelihood a whitetail will rub on it. Apparently, like appealing cologne, whitetails like to carry the scent of forest on their body.
