Perception & Detection - Where humans might fail

If you happen to have read our blog over at http://simplysasquatchradio.blogspot.com you will find some interesting questions raised about the way we perceive things. Animals seem to have a sense about them that we do not share. Whether that be advanced detection by sight, smell or sensitive hearing, there may also be a heightened awareness that we do not know about. Would a sasquatch use this to it's advantage? What do humans do by habit that would keep them away? And what do we do that attract them? Are we looking in areas that we think they may exist when all along, they have the upper hand and remain hidden amongst the forest canopy blending in with nature?
