Good choice, Cardeer! You did the right thing. Being a good and ethical hunter, requires choices and takes discipline! It is an easy choice when others are around, but its what we do when no one is there to see what we do that makes us who we are. That is what determines what type of moral and ethical caracters that we are!
I have hunted for years and have NEVER been checked by a warden, (fishing, I get checked a lots!) I could have taken a trophy buck a few years back, last day of the season too! But I did not have a tag for him. I thought about it, and figured I did not want to see an illegal deer on my wall, or even in my mind for the rest of my life! Did that make me a great person or hunter? No! I simply did the right thing!
You did the right thing! Now, since he ws not disturbed, you still may have a chance to get him with a bow. Or maybe in gun season, if you have that option! Whether you get a chance at him or not, you can rest with clear conscience!
Good luck! Remember, good things come to those who wait!
