I was just over in the Frankfort, MI area and the Traverse City paper
was going to carry a story the day after we left about soaring in the
Sleeping Bear Dunes area. It also mentioned a book coming out about the
same topic.
Does anyone know anything about the name of the book or where one could
get it?

I did see and take a photo of the National Soaring museum plaque in
downtown Frankfort.
