Query: Hike Las Vegas, but not with this book.

I tried to use this book. However, the route descriptions are poor, and the author seems to have trouble telling north from south. There are too many errors to be typos. The area has some great hiking, and the book points out some good ideas, but be sure to take your topo map and compass! I thought about selling the book on half.com, but I would feel too guilty selling it to someone with less outdoor experience than I have.
