Exploring the vast, endless expanse of Namibia

This evening, sitting outside our rented cabin on a farm in the Erongo Mountains of Namibia, south-west Africa, I see two swallows touring the sky and wonder, fancifully, if I might be seeing them soon again in west Cork.
Irish swallows spend the winter in Botswana, next door to Namibia, and would, about now, be beginning their long trek to the site of their nativity in some Irish barn. Our flight home, which we begin tomorrow, will take 28 hours to Dublin, including stopovers in Botswana and Ethiopia, and six more to our front door.
