Query: Great guide...

This is an excellent field guide for beginning herpers. The photos are excellent and it even has pictures for the different color variations of certain species. The herps are organized into groups such as striped, venomous, lungless, treefrogs, etc. and then they seem to be ordered by color. I have used this book to learn about what I should expect to find in places I've traveled to, where to be careful of venomous snakes, how where and when to find herps, identification and more. I even used this book last November when I went to Dominican Republic and it helped me in indentifying some lizards. I highly recommend this book for beginners in field herping. In my opinion the price is worth it just for the wonderful pictures this guide has.
