In October, Winnie-the-Pooh fans all over the world will celebrate an important date:  the 90th anniversary since the publication of A.A. Milne's first book, "Winnie-the-Pooh" with those charming, iconic illustrations by E.H. Shepard.

You might think this book - and the release two years later of "The House at Pooh Corner" - is all about childhood imagination, but did you know there is a real Hundred-Acre Wood? 

Kathryn Aalto, author of "The Natural World of Winnie the Pooh," joins Insight to share some of the magic behind the enchantment.
