first i would study topos and ariels of the area....once you learn to use those tools, scouting time on foot is rather easy...

then id go into areas that caught my attention(usually funnels and pinch points) and go in and see what it looks like....where the food is and where the bedding areas are....even then i can usually tell by ariels where likely bedding and hardwood areas are so im 1 step ahead...and knowing the likely prodiment wind of the area, it helps even more.....
