I generally do not as I am not required to by law. However, there are times when I feel it is appropriate, like when I'm in a heavily hunted area. Or this year I was on an antlerless elk hunt, and my dad pointed out that the hood on my coat looked just like an elk's mane (by golly he was right). I definitely draped the orange flap from my pack around the hood.
Wanted: 50 Beowulf Brass, .500 cal bullets
