I can not speak highly enough about how great this book was. If you are a fan of the show, you will love the behind the scenes. If you are a fan of paranormal stuff, you'll eat up that aspect. If you love to travel, you'll love the locations and insights.
The very best part of this to me was the deep look into the theory behind why traveling is important that Gates brings up. This book really got me thinking about how important life experience is and why it is important to see outside of your norm.
