Maybe he is just a really good hunter! He may pay attention to minor tid bits that get him success. That being said, with out knowing that the bucks were there to be had, maybe it all comes back to scouting during the summer. Looking at 1 pic does not tell you how much time a person put into hunting a buck!
He looks like a young guy, prob no kids, hunt as much as he wants....
WOW, WOULD I LOVE THAT MUCH TIME!!!!!!!!!!!!
