As a 20+ year resident of Arizona, you wouldn't think that I would need this book. I can say that I have driven around, across, and through most of the state, but even I learned a lot from this book. The first chapter introduces the state and provides some history that I would imagine most residents don't even know.
All told, I think this is a great book for anyone considering a visit to our fair state. The first characteristic of this product that struck me was that it is FULL color throughout. Not just a few select pages with photos, but the ENTIRE thing. There are so many beautiful places around the state, and this book has pictures that highlight each destination. Even if you're just visiting to play golf at one of the bazillion courses in the Phoenix area, this book can help you: look up "Golf" in the index and locate the "best courses" list.
What's more is that it also has four recommended itineraries depending on the time you have available and your situation -- 1 week, 2 weeks, family, or southeastern Arizona. If you've never been to Arizona before, hitting the 1 week route will give you a taste and get you to the major attractions. (Arizona, not Colorado, has the Grand Canyon. The Colorado River flows through the Canyon and seems to cause a lot of confusion.)
For those, like myself, who spend a lot more time here, or for those who are more into nightlife than outdoor activities, this book also provides guidance on where to stay, where to eat and drink, and where you can catch plays or visit museums.
This thing is packed with helpful (and spot-on) advice , reviews, and other ideas for planning your trip. Sure, you could fly to Phoenix then drive straight to the Grand Canyon, but wouldn't you like to stop by Sedona along the way if you knew it was just a bit out of the way? Would you rather take the interstate or the scenic back way? It all depends on what interests you -- and you can determine that by perusing the material in this book. To help you plan, there are many useful maps in the book, including a tear-out "pocket map."
I plan to use this book to plan my next weekend trip.
