The wild card for coyotes in this part of the world is wolves. Predation of coyotes by wolves is a thing, but, not totally understood.



I suspect it is only a matter of time before some meth loser who gets in over his head in the northern third of this state has a wolf encounter, likely brought on by hypothermia and not being prepared for the conditions he or she finds themselves in. The backward nature of the state of Minnesota is such that they named a hunter walking trail after the last meth head who never understood the Boy Scout motto (be prepared) in northern Minnesota, and ended up wet, cold, and alone on a night he should not have.

Hard to get through life when you die of exposure.

Best,
