Yeah I've heard and thought the same thing. Bright colored kids back packs are a lot less noticeable too, and if your car gets broken into, is less apt to be stolen. If you look all tac'd out, you will be a target. Same thing with carrying an obvious rifle. Consider instead a Draco pistol AK or AR pistol or Keltec PLR16 in your pack, and a pistol concealed but fast accessible.
