Query: This book looks great.

I ordered this book for an upcoming hiking and biking trip in the Arches and Canyonland areas. We are striking out on our own after using a guided tour last fall. We are excited and apprehensive that we will not know where to go. This book is very detailed about the trails and we are now more confident about our adventure. I am glad that I ordered it.
