Wow! If it didn't excite him, then maybe he is wanting a buck. Has he watched hunting shows before? All these hunting shows nowadays with big bucks are indoctrinating that you have to kill a big buck. Maybe deer hunting is not his thing. Take him duck hunting and you may just create a monster
May take him squirrel hunting also, because you actually 'hunt' the animal. You have to see them and be quiet stalking them.
No offense, but I have been in that situation a hundred times in a big box stand overlooking a food plot or corn feeder and it doesn't do it for me either.
