When I reached the bottom. (Finally). I realized I had no shot. .I needed to belly crawl under some burnt and blow down timber to close the distance to the trail I thought he would approach on. After some time and some tricky manuevering I was in a little depression behind some lodgepole looking down the draw, at the ready. Well, I see movemnet and here he comes on the wrong side. On my right I see him approaching, I am on the wrong side of the tree and he is looking right at me. Aaron cow calls and the bull lifts his head to bugle, it gives my a chance to move around the tree and get ready again. The bull follows the trail I am watching but he is in no hurry, I had a shot at thirty yards but I didn't want a quarterin to shot and I thought he was a bit too far. He stopped broadside at what I thought was twenty five yards or so but he was behind some spruces. Only his shoulder was visible. He was leaning forward and back, barking and bugling.. I would draw and then have to let down because he wouldn't move that shoulder forward. Finally he took a step with his far side (right) leg and I thought whne he moves forward again this is my chance. He did lean forward to bugle, the shoulder cleared the opening and sometime after that I saw the arrow bury in him. He raised his head, took a few steps forward very calmly, looked around walked up a five foot rise in the terrain. At hgis point I could see blood pumping out his side where the three-blade VPA entered. He wheezed and I saw blood come out his mouth and nostrils. He turned away from me and walked two more steps and collapsed. I broke cover and sigalled Aaron that he was down. We shook hands and went and got the girls. What a hunt.
