RE: cant stop the buck fever
It will get easier as you go. You will always get excited (hopefully) but learning to manage it is the trick.
I have been bow hunting since I got out of the Navy (1989) and have killed many deer with my bow. Just this year I had a 9-pointer underneath my stand. He didn't provide the best shot, but my anxiety (buck fever that is) definitely played a part in my hurried decision to make the shot I did.
In short, I botched it big time. I completely missed him. I practice that shot and thank God I did not injure him.
But I know if I wasn't out there that would have never happened to me. That is something I would regret for the rest of my life.
Never say die.
