I was about five or six years old when my father arrived at our garden gate one day, carrying a large geographic globe. It was wonderfully constructed, the kind of didactic tool with the world properly tilted to illustrate Earth’s true north. … We spent that entire weekend spinning the globe around and around. My father would patiently explain each country in great detail. … Looking back, I swear it was in that instant that the little travel flame started to burn in my belly.
