I will be ready. But for me it's mostly about getting them so close that it would be very hard to miss.
I've taken 9 deer with my bow in the last three years, and 8 of them were between 10 and 20 yards.
From 15 - 20 yards I REALLY like my chances on a broadside or slightly quartering away whitetail.

At that distance I feel like there is just no way I'm going to miss.
