I have only been able to get out a few hours here and there during the rut due to work and the new baby. I am off this week so I was hoping to get some time in a tree. Looking at the weather forecast it showed Monday being the standout day of the week with a low in the high 20's overnight and the high only reaching around 40. I decided I have been saving up my points for enough time and felt my wife out on the idea of an all day sit on Monday (I usually have at least a week worth of all day sits at this point in the season, and haven't got one in yet this year!) and she gave the go ahead. I settled in the tree about 45 minutes before shooting light. This is a rare spot for me, it is a small piece of a WMA and I am hunting about 150 yards off the road. I'm in a funnel between a thick swamp and a brushy thicket that is frequently covered up with rubs and scrapes. As far as I can tell from scouting and observation this little piece gets little to no bowhunting pressure but gets hit hard once gun season opens up. This year I am just happy to get out in the tree and I went into this hunt with lowered standards and just looking to take a good opportunity. The first couple hours went by with only the million or so squirrels keeping my head on a swivel. Around 7:45 I hear something in the swamp and look up to see a 200 pound bear coming my way. He walked right by at 7 yards and stopped, twice giving me a perfect broadside and quartering away shot. If this was only our fall 2016 bear bow season!! He moved off and I settled back into the waiting game. Nothing more happened until 9:45 when my swivel head caught a body moving in the swamp. I grabbed the bow and moved into position for that direction. It was a buck and he was on the prowl. I immediately noticed the beautiful light colored rack on him. He moved out to the edge of the swamp and started to quarter away from my stand at about 50 yards. I was starting to reach for the grunter to get ready in case he continued to move off when he stopped and stared back in my direction. At this point he was directly downwind of me. He suddenly turned and starting coming my way. I drew the bow when he went behind a tree and of course he stopped again. I was holding the bow back and in a pretty awkward shooting position at this point due to the lean on the tree, so I was just hoping he would step out. Well he took a few more steps and stopped in an opening quartering away around 15 yards. I put the pin behind his shoulder and let it fly, but immediately knew something was wrong as my arrow hit way back. I was immediately perplexed as to how I hit so far back as I watched him run off and stop. I could see less than half the arrow sticking out and he crashed to the ground. I could also see blood pouring out but he got back up and wobbled off behind some tree's where I couldn't see and I heard crashing again. My first instincts were that the deer was down, but how? I thought that I must have hit the femoral artery. Since I did not actually see the deer go down for good I decided I waited 45 minutes in the tree and decided to back out for a few hours until after lunch. The deer was either dead and laying over there or it was a gut shot and I would have to give him overnight. My plan was to sneak in with bow ready to the spot where I saw him go down. If he was dead he should be laying right there and if he wasn't there I was going to back out and come back the next morning. I picked up the blood trail at about 1pm and it was like a red carpet. I got to the spot where I last saw him and there he was laying just another 15 yards away. While gutting him I found that the arrow had come in pretty far back and went up and caught the middle of the liver and back on the opposite lung. I could not tell if I hit that artery but based on where it entered and the blood I am pretty sure I did. I couldn't find or smell a hole in the intestines and it did not puncture the stomach at all. I am not exactly sure what happened that caused me to hit so far back. When I went to where he was standing I could see a bunch of small twigs that I could not see from the tree. I was also in a weird position due to the lean of the tree and was kinda of hanging on the downward side of the lean but shooting back on the opposite side of the tree so it is also possible I caught my coveralls on the shot. I have practiced shooting with coveralls and shot many times without issue, but its possible the weird position got me. Either way I had a little bit of luck on my side today
