No kidding. Several of the areas I used to solo hike in Washington state are now not quite so safe anymore. Even in my resident state of Idaho there are Fish and Game people who used to solemnly insist that wolf introduction had little impact on elk herds. Such as these: 
That picture is of 19 elk killed in a single evening by wolves in Wyoming. The carcasses aren't chewed on for food. These days they're authorizing wolf hunts to attempt to recover. They're magnificent creatures and I'd hate to have to shoot one but anyone who announces that they aren't dangerous doesn't know what he or she is talking about.
