Mine was Thanksgiving morning 1984 with an old Mossberg 500 12ga. At the time in Indiana you could not shoot does with a firearm and bucks sightings were few and far between. I was sitting in a fence row that seperated a cut corn field and a CRP field. A doe came running across the CRP field about 30 mins after first light and stopped in front of me about 80 yards out. She stood motionless for better that 10 mintues watching her back trail, then he came running. At the time I had not idea how big or small he was, I just knew it was a buck and I was going to shoot. He stopped, turned broadside and I let 3 slugs fly as fast as I could pull the trigger. The two deer ran off and in a valley, I seen the doe come out, but not the buck. With snow on the ground, we found no blood at all, but a quick search of the valley found my first deer/buck. He would have been a really nice 10 pointer, but his right side main beam was broken off just a few inches off of his head.
I am not much of a gun hunter any more, but I still think about that every year. The first one is one you will never forget.
