One of my not so secret tricks for public land is when an area fills up with those metaphoric 'no trespassing' signs or tree stands, the best places to hunt is where no one would want to or cannot put up a tree stand. The other thing is, always remember that the thermals are wandering tricksters on ravined slopes in the early morning or the evening, even if there is a soft breeze, they do what they want. I you have a steady direction to the air, a higher more level area more predictable in your immediate area. In the evening with little or no breeze, scent will almost always seek the lowest levels, but it does not always take a straight path to get there. .
