I was fishing the Manitowish chain last week and came upon this while working the shore of Alder Lake. Maybe a members boat?
There's a family on that chain that has two or three daughters. If it is the same boat, it gets a real workout in the summer. Per a property owner on the river up there, they keep Greer's Pier fuel men very busy. I can contact the guy I know and see if that's the boat.
