There is at least one error in this book. Trip 2 lists NG Map 792 but it should list Map 791. I'm in my mid-50s and have been backpacking regularly since the age of 10 in areas that include the southern Rockies, Frank Church, and Northern Cascades so feel qualified to write a review on this book compared to many, many others I've read over the decades. This book covers trails like the others but they are all backpacking vice hiking day trips or mixed hiking day and backpacking trips, and the concentration is on loop rather than out and back, and shuttle trips. If you hike alone, don't like to cover the same ground twice, or want to avoid the shuttle task loops are the way to go. I also find this author does a bare minimum of pandering, unlike rival authors.
