I haven't hunted as much as a lot of you, but all of my hunting has been in the West, except for some hog hunting in Texas. West Texas, that is. All the game I've taken has been at pretty short distances, by Western standards, all less than 20 yards, although I'm prepared to take shots out to maybe 30 yards if the occasion presents itself.
All the game I've taken has been dumb luck on my part. The deer in my avatar, for example, was taken when the sun was going down in southern New Mexico. I had given up hunting for the day and was walking back to the truck. I certainly wasn't trying to be noisy, but I wasn't trying to be stealthy either. I was just walking along quietly, when I came around a big manzanita bush or something and saw a big deer from the neck back, with his head down behind another bush. He was chomping on something, and the noise of his chomping was louder than the noise of my walking. I could even hear the chomping myself. I was able to take my time drawing and shooting, just like I would at a 3D deer target, and he never knew what hit him.
At least two other times, I have fallen asleep in my stand or blind and woke up to see a deer browsing less than 20 yards away. Probably it's a good thing that I fall asleep, since I am so fidgety that I probably scare them all away when I'm awake.
Another time, I was riding around with a rancher in a light drizzle when he spotted a nice blacktail that seemed to be headed toward a stand of his. He drove over and dropped me off, and I didn't even have time to lock in my safety strap before the deer came right under the stand. That time, my dumb luck was that I managed to shoot the deer without falling out of the wet slippery stand!
There are other stories of my dumb luck, but these are enough to give you the idea that even a blind squirrel finds an acorn sometimes. In most of the places I hunt in the West, it is impossible to walk without making noise, so it seems to work out best for me to find a likely spot and then wait and see what happens. If they don't see or smell you before you see them, then they might eventually work within close enough range to get a shot.
