Ok, I'll take the bait, I don't get a buzz from letting one walk, which I do fairly often. There is the satisfaction that you could have had a successful stalk even though you chose not to, but definitely not a buzz in any way shape or form.Let me put another slant on this:
I think that there's greater pleasure to be had not from killing the deer you want to kill, but from keeping the deer you want to keep.
When you look down your scope you make a life-or-death decision, and I defy anyone to deny that they get a buzz out of letting one walk on when they could have squeezed the trigger.
If it's the act of killing things that gives you your buzz then you might just as well get a job in an abattoir. You are not worthy to call yourself a hunter.
To be honest the only time I get anything I would describe as a buzz is after a particularly long or tricky stalk, the kind where you spot a deer a long way off and have to work the ground to get in, or they are close but aware and you have to outsmart them, and that stalk is then successful. That lets anticipation build and feels like you have achieved something, rather than spotting at 200 odd yards and shooting them off sticks, which I also do quite often.
I honestly think people are in denial if they don't view the kill, or the potential to make a kill, as an important part of the overall experience and therefore enjoyment, as said above, it is simply not hunting without it!
