Lonely Planet Africa (12th ed.)
I crossed Central African Republic, Congo-Brazzaville, and Congo-Kinshasa for this continent-wide tome. I also condensed my Sierra Leone and Uganda chapters from the West and East Africa books into this one.
Lonely Planet Mexico (11th ed.)
I covered the Central North and Northeast chapters, which comprise the fascinating but seldom-visited states of
Chihuahua,
Durango, Nuevo León, Tamaulipas, and Coahuila.
Lonely Planet USA (5th ed.)
I scoured the oft-derided but oddly attractive Great Plains: North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Missouri, and Iowa.
