My co-worker was out in the woods (GMU 121), when he heard a wolf howling. He started back to his truck, he let out a howl and it was coming in to his howling. It appeared in the timber 30 yards away! He ran to the truck and the wolf trotted 50 yards away and continued to howl at him, he took this video with his phone. I didn't believe him till I saw the video. You can hear the wolf howling faintly in the background! Awesome!
