Hunting from the ground is much more fun in my opinion, although it probably is not as productive as climbing a tree. I enjoy the freedom that ground hunting affords, and I am impatient enough that a few hours in a tree becomes boring to me, unless there is a non stop parade of animals to watch. To those who spend all day in a tree, I say enjoy it, but that is not my cup of tea. Although spot and stalking virtually guarantees sights of white tails bounding away, or elk crashing through the lodgepoles, it is still a lot more fun than making like a bird and perching in a tree for hours.
That being said, you will still see me climbing a tree from time to time, because it can be very productive.
