>>980704One of the memorable stories I read involved a guy riding along around dusk, already miserable and exhausted half out of his mind. He's following the track of a dogsled, and catches a glimpse of eyeshine. Then he realizes it's a fucking wolf by the side of the trail and FREAKS the fuck out - wolves in Alaska are not exactly solitary or tame creatures. He books it as hard as he can for as long as he can and basically spends the next couple hours wondering if he's about to die violently.
At some point well after the fact, he learned that it was the corpse of a wolf that someone had left by the trail. Perhaps as a warning, perhaps as a practical joke.
