The family that walks together, talks together and sometimes even finds “cool floaty things” in Lake Michigan. Together. Such is the experience of the Young Family — Tim, Kathy and their kids, Stella, 15, and Connor, 10. The aforementioned “cool floaty things” — Kathy’s phrase — turned out to be leg bones, the remains of a white-tailed deer they found during a spring walk in their own backyard, the Sleeping Bear Dunes National Lakeshore.
