RE: What is your best skill???
My best skill is resiliance (spelling?), that is, I keep going back out, even when things look, bad. I got my rifle season deer by going out on a cold day with 40 mile winds and got down in a creek bottom. I wore a huge face muff and was going to hunt from 2pm until dark (6ish), but got the deer between 4 and 5. I just got out there when few others would and got my deer.
Also, I know my hunting land very well. I look where trails come into my stand, and I get to know where they come from so when it's hunting time, I understand what is just around the bend/over the hill/ through those woods/down or up the creek, etc.
