I know the feeling of getting busted in the dark, and it sucks. It happened to me more than once. Last year in archery heading in at dark crossing a field for about 200 yards all is silent and I'm feeling good then I pause at the woodline before heading into the woods all is quiet, one step in the crispy leaves and deer are blowing left and right bounding off. Ahh what a horrible feeling. You question yourself if its worth sitting there after that happens. I went in anyway only to leave several hours later without seeing anything. Bummer.
