I came close one time on a nice buck during the rut. I was walking in, just barely light out. The buck heard me walking in the leaves and charged at me with it's head down and grunting the whole way. I had my climber on my back. I got an arrow nocked and he stopped behind a tree, looking around it and glaring into my eyes at 15 yards. I aimed for his neck but stuck the tree instead. He did a backflip and came closer! I tried to nock another arrow but he turned and walked away slowly with his hair standing up and stiff legged. I still get goosebumps when I tell the story. It was a great experience.
