Finding your way around Oman (Muscat)
I found a book that was new to me, at the bookstore in the airport which contains over Protected content maps within Oman (often difficult to find!!), and lists/describes almost Protected content to visit. Certainly, by far the most comprehensive I have found, though it does seem to have some advertisements inside. It is called, "Official Guide and Atlas Oman". Certain to help the newcomer here, or visitor, and even the longtime expat.
