Say you went out hunting rabbit, what would likely happen?
You could go out any day of the week and shoot a few rabbits? You could go out and probably shoot one? Fifty-fifty on even being able to shoot one? You manage to shoot a rabbit one time out of ten you go out?
Assuming you pretty much know what you are doing, have the right equipment, are a good shot, etc. How important is a rabbit dog/dogs to the process?
