I hunt deer almost exclusively from the ground, for the reasons some of you have already stated. I hunt from brush blinds a lot, but I enjoy still hunting too.
I love the rush of having them close, and at eye level, and I don't like the steep angled shots offered from tree stands a lot of the time, though this can be evened out some by keeping stands lower. when I'm on the ground, and do things right, It's in one side, and out the other, which usually makes for a much nicer blood trail.
I hunt areas around home, that other people hunt too, and I've had several tree stands stolen in the past. There's nothing like getting to your stand with high hopes, to find your stand gone.
I guess the main reason I hunt from the ground, like I said above, is for that up close and personal, eye to eye excitement. Getting them close, waiting for that perfect shot, and then trying to draw without being seen. That's what does it for me.
