Peg Bowden, RN, MS, a retired public health nurse, lives in the Arizona borderlands (a sort of third country, as she puts it) with one foot in Mexico and the other in the U.S.A.  She volunteers at a migrant shelter in Mexico attempting to understand why thousands of people are willing to risk their lives crossing the Sonoran Desert into the U.S., where they are despised by so many.  She has written a book, A Land of Hard Edges, which reflects on the complexities of human migration.  Peg lives in a rammed earth home with her husband, Lester Weil, 2 dogs, a feral cat, and a lot of open range cattle.
