Makes me wonder too. They have found tons of evidence and when I am near Traverse City I usually will be fishing in forested areas around the Leelanau area, and I heard a few roam around the sand dunes up there. I'll have to keep my eye out. I heard of them attacking dogs and sightings are prevealent in the UP and LP.
Well, Michigan sustains a population of wolves, bears, moose, elk, and now cougar....wow, I didn't even think of how wild my state is!
