We were actually on yet another Rick Steves Walk, the "Dolce Vita Stroll," which headed down the Via del Corso from Piazza del Popolo, with a slight detour to see the Ara Pacis and Mausoleum of Augustus. The time to do this is early evening, when Rome's youth go for a stroll, called the "passeggiata." It's the time to see and be seen, to be trendy and to whisper catcalls ("buono/buona") to the young and fashionable.
