An account in Mackinac County, Michigan

I was steelhead fishing in the U P michigan, 8:00am. After two days raining only tracks on the river were deer, and mine...until I found two sets of barefoot tracks. I have pictures. One set was larger than the other. What bugs me is, I was two miles upriver from my truck, nobody around for miles. It was 5/10/15, 40 degrees out, water temp about the same, and they crossed the river...there isn't anything over there for miles but woods and the river is four foot deep right there. Neither track had an arch, the tracks were flat and broad.They sunk in the wet sand way deeper than mine. They were not human. If someone would call me, I would be happy to share the pictures, and the rest of the story.
