I sense that steel baron Andrew Carnegie would disapprove of my scooter-suitcase. A handoff from a friend, with a plastic body and leather cover, its primary metal component (the ball bearings controlling the pop-out scooter) jams en route to the industrialist-cum-philanthropist’s adopted city of Pittsburgh; it’s subsequently mangled by well-intentioned airport security until nothing but a shattered mantle remains. Lugging this failure of industrial design across multiple terminals leaves bruises that will run down my legs for the remainder of the trip. Fortunately I have trousers. Otherwise, like the rest of us dropping in from an unseasonably steamy New York, I’m comically unprepared for this brisk Mid-Atlantic fall weather. “Put on a sweater,” a woman calls from across the street as I attempt to photograph the neon Heinz Ketchup display outside the Heinz History Center next to our hotel. . .
