I love all the above but I must admit it's the kill I love the best when all the hard work and money spent on gear and such comes together. I still get an adrenlin rush, even when taking a doe. If I ever lose that aspect of the hunt I'll quit hunting and just hike & camp.
Where I hunt I always see deer. But when a good mature buck shows up it's all I can do to calm myself down to make the shot. That's what I hunt for. Well that and the meat from the does and hogs. If I had to kill something in order to enjoy hunting I would have quit a long time ago but the kill is still my favorite part.
