Well glad to see that you had a good ol' Texas time. You got the fever now don't ya! At least they were not to hard on you for your first hunt. It sounds as if you picked a good group to start with. Congrats and don't beat yourself over the 6 point, maybe next time it will be a 10 and your heart will really jump out of your chest.
I would imagine all of us on here could write books about shots we should have or could have took but it is all patience, practice, and enjoying what you do.
