The wind is the most important factor, camo is important tho. I had a bull bugle at me last year and was walking strait up the trail at me, I had to turn real slowly 180 degrees to face him. Every time he put his head in the brush to scrape i would sneak up 5 or so yards. did that 5-6 times and he never knew i was there. I dont think i would have got a shot if i didnt blend well.
