Query: Great for nature lovers and armchair traverlers!

Fabulous book! The text is very interesting and educational, and it explains the scientific aspects of the National Parks and their land very well. The photos are gorgeous and made me want to visit every single park! :-) They really show some of the awesome beauty of God's handiwork. I highly recommend this book to all outdoor enthusiasts, lovers of nature and science and fellow armchair travelers. The book also contains helpful contact information for planning a visit to the parks. A great read and a great book to enjoy!
