A Canadian motorcyclist says he was chased by a very big gray wolf. It might just be another story, except, when he realized he could keep ahead of the animal, he stopped for a second to whip out his camera, prodcing the fascinatng photographs here.
Wolf attacks on humans are very rare, though they have happened. The doesn't read like a case of attempted predation, though. I would hypothesize the wolf had been domesticated or at least acclimated to humans, maybe even owned by someone who rode on a motorcycle. The other traffic on the road should have scared off an animal who was just playiung, though. For some reason, I speculate, this wolf thaought this person was his pack leader or at least would feed him.
Of course, I could be wrong.
