RE: keep passing?
I have a system that hasn't let me down yet! It's called the WOW factor. If when you first see the buck, the little man in your head says "WOW"! You try and get a shot! You may even spend the rest of the year or 2 looking for him. If your first thought isn't WOW, you'll never truely regret your decision.
Now the buck that triggers the little man to say WOW will vary for each of us, based on expirience, kills, or state of mind. But when the little guy speaks...ya gotta listen!
