The problem is, you will rarely see them unless they want you too. We've had a few of our biologists stalked, one right up to his truck. He said he about pooped his pants once he got inside.
With more and more cougars all over Washington, they are becoming a bigger problem so it's absolutely something to be aware of. If you do have a problem with an aggressive cougar, make sure you contact Fish and Wildlife right away (if you are in imminent danger 911!).
Unless it weighs a ton... it's just a horse. Draft horse motto.
