Hunting on the ground is really not much diffrent than hunting in a stand, just at a lower elevation. All the same methods apply. Be aware of the wind, blend in with your surroundings, avoid noise and movement and be ready when the time comes to make a shot.
I like hunting on the ground, although I do use stands as well. I think hunting on the ground can give you more freedom to hunt various spots without a lot of planning ahead. Wind changes, make a move...weather gets crappy, make a move. No worries about wether or not a stand location will work or is-or-ain't in the right place. Ground hunting, especially without a pop-up blind (just you your bow and a seat) is about as free wheelin' as you can get.
I hunt stands, I hunt blinds, I still hunt, and sometimes I just pick a spot, pile up some brush behind me and plop down on my seat. Simple, effective, easy...and enjoyable.
All that said, if you don't think ground hunting is getting the job done for you, do something else. Don't get all balled up on one technique just because you think it is MORE traditional or MORE better because somebody said so. The hunting thing is supposed to be enjoyable...have fun.
Good luck!
