footfalls and edges......so why use camo clothing in the first place? The wind, other critters, cattle, rain etc are continueously moving and stiring up scent and the foliage.
Nature is continually moving and changing. It does not sit still and stay semetrical.
Animals don't just know this, it is part of them. They do not walk into a field and think, "wait that leaf is turned over I'd better get out of here", it is simply how things are.
Now, anything that is not of nature, say your 4 wheeler parked under a tree is definately cause for alarm for any animal.
But you neednt worry about that because the thought and sound of a 500cc engine in the woods going to the deer blind is perfectly natural to animals. Besides, you look really cool.
Stop worrying about all these BS details and enjoy your hunt.
Which shampoo to use.....geesh...I'd swear I was in a beauty salon or ***** eye for the deer hunter.
