Gigantic Wolf Killed in Sun Valley, Real or Fake?

Check out how BIG this wolf is! This picture has been circulating via Facebook and text messages. It is being said that it was hunted and killed in Sun Valley. If this picture is real, it proves that my fear of wolfs is totally realistic. Everyone tells me that wolfs have no reason to come into your camp unless they are really, really hungry. How do I know if they aren't hungry?

Do you think this picture is real or fake?
