The "clueless tourist" anecdote at the beginning reminds me of a time I agreed to meet a friend in Florence. We agreed to meet "at the David" - I was thinking the one in Piazza della Signoria.<p>It turns out there are not two, but three Davids in Florence. The one in the Piazza, the one in the Galleria, and a third one in Piazzale Michelangelo, made of bronze.
