I grunted a few times and expected to hear him blow out and run off, but he didn't. He came right back to where I originally saw him. By now it was light enough that I could shoot and I could make out his slender body and see that he was big enough to shoot. Only problem was, I still had my grunt tube in my mouth and my bow on my lap. The deer walked out of my sight window and disappeared. I could hear him walking around the back side of my blind, he was so close I could hear him breathing...This was a real intense moment, I could feel my heart about to beat out of my chest. Then more science.......
