Moving Day Theatrics

We're either naive or troglodytic, or both, but we had never seen the moving-day technology that we observed one morning from our ground-floor apartment in quartiere Coppede' (a corner of the Trieste area).  It seemed perfectly suited to buildings of 3 or 4 stories, which are very common in Rome, especially those with narrow stairways (not so common, in our experience).  In any event, we enjoyed watching the performance, a working-man's ballet.   Bill
