If you love the Au Sable, here is a chance to have a wonderful book, AND help the Anglers of the Au Sable with their on-going legal bills protecting the river.
The book is Seasons on the Au Sable, twelve chapters, one for each month. You can order it (or become a publishing partner) by contacting Rusty Gates.
