Next time dont tie it down,attach a heavy log to it or something of that nature that an animal the size of a coyote could just barely drag.That way they cant get the leverage to pull free and draggin it will make them tired and leave an easy to follow trail.Any smart coyote wont let himself get caught a second time though, not without an elaborate setup.I think it was a large coon,you said there was a fence.How high ? coyote would go under it,coon would go over it or thru it.
