I had a simular situation yesterday morning when I was going in to spread more corn out.
I looked up and at about 80 yds I seen this big brown form so I just froze.It snorted at me 5 times stamped its foot 3 times when I did not move it just walked away.
When they do blow at you they think something is there and are trying to get what ever it is to move.
Now if it blows and you see the white flag waving at you then you have been busted.
