A few weeks ago I watched a hunting show (whitetail freaks I think). They had some trail camera photos of an impressive buck, had an encounter with that buck the year earlier, and then found a shed. They mapped it out all the locations and found what they thought was the bucks bedding area. They killed that buck the first day they hunted that stand. I don't know if the photo or shed is more important, I would think it is all equal when mapping the deers core area. Either way, I would think you are on your way of getting close to this buck.
