RE: Public Land
One trick I have learned on Public land is to break it down. When I hunt I take 100-150 acre sections and master that area. I have setups for all the wind directions. I learn where to walk and where not to walk. I learn there travle routes, bedding area, etc.
Right now I have 4 big woodlots I hunt in Northern MI. In each of those 4 I have 2 to 3 sections I hunt and know.
