Iowa...that was a really good explanation, I think I understood most of it. Camo or not, when you are skylined your every movement is a billboard. With your back up against a solid object like a tree trunk, big ol' rock, or a deadfall and your movements just don't stand out as much. Another advantage is the bullet/arrow/shot stopping properties of what you are leant up against....not everyone out in the woods is paying attention to detail.
