I had closed the distance to about 40 yards when he started to get nervous, so I drew and held high, thinking my arrow would drop significantly. I should have trusted my instincts, as my first shot hit him where I was aiming, right in the hump. He ran a few steps out of the slough and stood there looking around, wondering what had just stung him. I wasted no time and put the second arrow right in his ribs. He spun around again, acting like he didn't know what was going on. I crept closer and when he stopped I put another arrow in his ribs. He ran a few steps and stopped to look around yet again! Now, from about 30 yards, I slipped another arrow into the boiler room. Almost unbelievably, he ran a few more steps and stopped again! I was down to my last arrow, so I worked in to about 20 yards and threaded it through the brush into his lungs as well.
