Carter is one of my all-time life-long heroes because he tells it like it is no matter what and he favors few. In fact, he was rather indifferent about wolves until he had to remove an entire pack (this after capturing and placing them in YNP and the Frank Church himself) because they ate some kid's 4H goat or sheep. He wrote his book about the whole thing from his beginnings to when he had to kill that whole pack... it changed him profoundly. Since then he has been an advocate of the species and has never looked back. And he's not just a hero for that but a number of things that I know about him. But if ever there was a true-hearted and realistic, honest person alive, it's Carter. He's about as up front as they come. Now he trains Tribal F&G agencies in wolf management and gives lectures all over the place, including Internationally, he's a great advocate of non-lethal management tools and helped develop many of those recommended by wolf advocates.
You should really read his memoir, he's a good writer. I've known him since years prior to the removal of that pack and we are still very close friends to this day.
And while I'm at it, real bad news out of the Frank Church:

Sadly, the guy has been happily killing off wolves, seven confirmed and more not yet tallied as of earlier today.
The guy is a member of and probably recommended by one of the most vehement wolf-hating bunch of scallywags in Idaho.
