you know i hunt an extremely small plot of woods in NC and for the longest time saw zero sign of bucks. No scrapes, rubs, nothing. THen one night i saw a 13 pt and some cow horns. Eventually found some scrapes and rubs. One thing that helped me is that I made a mock scrape right where I was hunting and shortly later had scrapes and rubs right there with the mock.
By the way, I missed the 13 pt with a bow (first deer I had shot at with a bow, got excited and used the wrong pin on my sight. You learn from your mistakes) and havent seen it again. A week ago (about 715pm) someone local shot that deer with the aid of a rifle and a spot light. Gotta love some ignorant people.
