My best skill is sitting. I practice this all year long, and am currently practicing right now. I love sitting.
I really haven't had any deer that I have shot due to some "best skill" aspect of the hunt. All of my deer have been "right place at the right time."
I can walk through the woods fairly quiet though. I snuck up on a buck and a doe during the early T-zone season this year. The buck never saw me, but the doe saw me when I pulled up on the buck. Unfortunately, I never had a chance to get a shot off, but I'm next to positive he's the same guy I picked off a couple days later.
