I hunted a property that I couldn't pre-scout or set up stands on (Navy base rules). The day I was able to get out I set up a ground blind. Three huge bucks were heading my way but they stopped at about 75 yards I believe because they saw the blind. I grunted and one of them started stepping closer but another walked off in a different direction and the other 2 followed. I believe if I had that blind in place for a couple of weeks things may have turned out different.
