Hard to pick a best decision but this one stays with me.
Once when I was about 22 years old I was deer hunting out of an old tree stand. Last day of the deer season. I just wanted some meat. I had both buck and doe tags. About 125 yards out in could see a deer walking through the trees but I could not discern whether it was a buck or a doe. Watched it meander along through the trees with legs moving along and occasional open spots through the trees, and I thought to myself, what do I care, next open shot through the trees where I had a good mid body shot, I would shoot it. But when the opportunity arose I could not bring myself to shoot. Mainly because I just was not 100% sure what it was. So I crawled out of the deer stand and decide to put a stalk on it. After about 10 minutes I got ahead of it and was waiting for it to walk into a small clearing where I would have a great shot. In walked the prettiest little Bull calf you ever saw in your life! Exact same color as the whitetail deer on the property. That rancher would have kicked my butt, kicked me off that Ranch forever and I would have had to pay for that calf. No money would have replaced that little bull calf!
just solidified again, that you do not shoot unless you know exactly what you are shooting at. I will never forget it.
