That is weird on that G3. Nice buck indeed. That gets us off and rolling for sure. I'm off Halloween and plan to get up close and personal with one. I saw a nice mature deer on the way to work this morning. They are on the move here in SE KS.
I had the same thing happen two year ago. I shot a nice 140 class 8 that was with a doe and then just when I was about to get down here comes a 160 class 11. I just watched him walk by at 20 yards and go and take that dead bucks doe. Pretty neat.
