Query: A great adventure

Skillfully written and edited to perfection, this book is a joy to read. The story is a thrilling adventure that's hard to put down; plan on pulling an all-nighter when you read it. In one year, Kenn Kaufman traveled 80,000 miles, saw over 600 species of birds, and spent less than $1000 in doing so. I'm more of an armchair birder myself, content to see the world's birds in books, and I loved being taken along on this amazing journey without having to leave the comfort of my own home.
