You're welcome. But I have no idea how many, or what kind, of changes Maddy made when she updated her book.
I was about to suggest that you contact Maddy, via her Flying Pencil Publications web site. But that web site is now inactive.
My only suggestion--if you want to reach out to Maddy--would be to contact Eric, on his Facebook page https://www.facebook.com/BestFishingInOregon. He may know how to contact Maddy.
