I once boarded a gargantuan cruise ship in the Miami harbor. Even from the highway we could see the giant No Smoking symbol painted across its hull. Approaching by foot with our suitcases, loudspeakers everywhere blared the good news: this was a non-smoking boat. Better: the boat’s construction dock had been a non-smoking dock. I was young, but even then I understood the folly of virginal girders, and that soon enough people would want to make everything virginal again.
