I have been hunting for over 25 years. Most of that has been on public land. My best success has been from being willing to get as far in as possible....as far away from other hunters as I could, and to find transitional spaces. Meaning the edges of fields...30+ yards inside the woods. The edges of where it changed from hardwood to softwood (pine). From normal forest to thicket, From swamp to whatever. identify those places and look for sign that animals are moving thru these areas then set up an ambush.
Good luck
