Being on public land I would find a travel corridor and follow it as deep into the bush as you can and then set up off that where you have a few good shooting lanes. Since it is public land there may be other hunters in the area so use them to your advantage. You may be as stealthy as possible but the other hunters may not be. Get into your stand way early and if other hunters start to move the deer around you will be ready. I have noticed with public land that many that hunt it do not do detailed scouting and often set up not far off the roads or trails, looking for a position of ease for themselves and not the best deer harvesting situation. These hunters will push the deer farther into the bush so use it to your advantage.
