I’m a bit late to post this, but the book is out! Check for “Our States Have Crazy Shapes: Panhandles, Bootheels, Knobs and Points” by Lynn Garthwaite on Amazon.com and http://www.bluespectrumbooks.com.
This book is the perfect gift for the Cliff Clavin in your life, or anyone who is curious about the odd jigsaw puzzle map of our United States.
I love this book! I keep giving mine away as a gift!
