This is why the sport is called hunting and not killing. However, you may see it differently there is just so many reasons folks hunt, of course harvesting game is the goal but sometimes it either just does not happen or in your case you chose to not shoot. Myself I just love nature and getting out to watch whatever happens to be in the woods that day is a satisfying expierience. If I happen to see a deer, which I do quite often, that hunt in my eyes was a success. Be patient and enjoy nature there is a lot more to hunting than just firing your gun.
