Nice deer but frankly I wouldn't call it hunting..sorry. Going out for a smoke and seeing a buck in your neighbor's field, grabbing your rifle and shooting it??? then going to finish the job with your shotgun!?! It was just pure luck that you shot him and possibly not even legally considering how close you were to occupied dwellings. Go ahead and mount him if you want but....if that's the case I could have mounted a nice buck I got with my wife's Chrysler Sebring a couple years ago. Same thing IMO.
I shot a buck that big this year but after putting in 126 hours in my tree stand. Now that buck was hunted as he was one of the 2 I was after all season.
