If it doesnt upset you that you wounded one then you shouldnt be hunting in the first place. It happens to all of us at one time or another. It will help you think harder next time to make a better shot. I have spent three solid days tracking a hit deer before finding it. It sucks because you lose three days of hunting but never give up. Yes I do consider the weather before releasing an arrow. I do not bow hunt when its raining very hard. I only take certain shots before dark. I try and shoot at least five or six arrows before every hunt. I set up a deer target right outside my garage so I can shoot right before I leave to hunt. Get yourself a Block target that you can take with you and shoot at before walking to your stand. Good luck..
