Hey man, I know the feeling. About a month ago I had a 130' s class 8 pointer walking down a trail and leterally had his front foot in my shooting lane. As he took a step I drew and one of the other bucks with him saw me and took off. All that buck would have had to do was finish his step and he was mine.

It' s a horrible feeling but look at it this way, would you rather have seen nothing again???? Good luck.
