I have seen a wolf in the wild in NE Washington. I saw it only
because it let me see it. I was walking quietly on a trail and
still didn't hear it, even after it came towards me on the trail
and then turned and walked away.

Head phones or not, if wolves or cougars are stalking you, it is unlikely you will hear them. Animals that can stalk creatures
as large and quiet as elk would have no trouble sneaking up on
a human if they desired.

Susan, you sound like the "stupid" police.
