First, I'd like to say that I don't really post ever, but I decided to share this story to maybe help someone else down the road. It was about 6:20 AM on opening day. I was hunting on a piece of private property in zone 2. I climbed into a fixed wooden stand that is covered in a green algae or slime. I had been in the stand a few times bow hunting with no issue. I didn't feel comfortable in the stand but decided to stay, instead of plowing through the woods to move to a new spot. So I am in the stand, but I remain seated. Before it gets light I try using my boot to skim some of this green off the wood so I am able to stand, which really didn't work. At first light I see a doe out of the corner of my eye but she is behind me. I have to fight to carefully turn my seat in that direction. I watched this doe for a few minutes as she keeps looking down into a swamp. A minute later I have a buck walking right to her. I took my shot and the buck goes down. At this point I'm excited and honestly cant wait to get on the ground. I figure I am going to gut the deer and head to the diner for breakfast. I get down to where the deer is laying and realize I forgot my pack, which has my knife in it. I know I should not have been in such a rush but I really wanted to be out of that stand. I walked back to the stand, climbed up, grabbed my pack, threw it over my shoulder, and started climbing down. I got maybe 2 steps down and my foot slipped and I am now hanging. I did not panic and was able to put my other hand back on the step, as I'm trying to get my feet back on. Just as my foot touched the step, the board that I am holding pulls loose from the tree and down I go. It really happened so quickly I had no idea what had happened at first. I was very lucky and landed straight on my feet. I had no pain at all but I was a little shaken up. I sat for a minute or two and still had no pain so I decided I was going to get up and get my deer. I took a half step and realized that I could not put any weight on my right ankle. I sat back down, took my boot and sock off, and realized that my ankle was swollen and bruised already. I radioed the guys I was hunting with and they all came running to me. I told them what happened and they went to get the four wheeler to get back to the house. Once back to the house my wife came and took me to the ER. Once there I had some x rays taken, which showed it was broken. Later that night I had surgery and received a plate and a few screws in my ankle. Moral of the story, I guess, is to following your gut feeling - from the beginning I didn't feel comfortable in the stand, something didn't feel right. If I had gotten down and moved to a new spot or taken more time descending initially (allowing me to remember my pack the first time), I may not be in this situation. A big thanks to the guys I was hunting with for getting me out of the woods and for dragging my deer and taking it to the butcher. Also, to my wife for staying at the hospital for 15 hours.
