"The beast is not shy, and visits most often under bright sun. While no one here knows what it is, they do have a name for it — the hyote, a combination of a hyena and a coyote."
UPDATE: Numerous readers have written in with reports that the "hyote" is actually a fox, dog, or bear with terrible mange. No matter the origin of the mysterious beast, I agree with this posting from the Fark forum: "We must catch it and learn from it."
