We hunt in the same place, every year. As such, we have learned the basic grazing patterns and natural funnels of the area.
It also doesn't hurt that most of the roads into that area are overgrown two-tracks from the lack of travel over them the last few years (used to be much more travel over them, but in the last 3 years, I think we are the only ones using those roads anymore). Most years we go up, you can still see our tire tracks and marks in camp from the last year.........and this last hunt we only saw 3-4 other people in our area.
It is quite nice to be the only ones out there, almost our own private game preserve.
