Observatories of the Southwest: A Guide for Curious Skywatchers is a new book by Douglas Isabell and Stephen E. Strom.
The book profiles Palomar, Kitt Peak, Lowell, Whipple, Mt. Graham, Very Large Array, Sacramento Peak and McDonald Observatories. Each chapter includes sections on the history, research and public outreach for the observatory being profiled as well as an interview with an astronomer that uses that facility.
I just got a copy today, so I haven't taken a good look yet, but if my skimming through the chapter on Palomar Observatory is an indication of what the rest of the book is like than I would say that anyone interested in visiting any one or more of the observatories included would certainly enjoy reading this book.
The book is available through the University of Arizona Press and other outlets such as Amazon.
