My favorite lame travel joke used to be: “If it’s Tuesday, this must be Belgium.” On the current voyage, the new one is: “If you’ve seen one Acropolis, you’ve seen ’em all.”
Except… The Greek word technically refers to the summit of a hill, with or without a temple on the top. Only if you’ve seen one Parthenon, one Ephesus, or one Olympia, have you really seen ’em all.
Anyway… Speaking purely as a photographer, you come to the point where you’ve shot so many photos of seemingly interchangeable ruins, that the tourists stop getting in the way and in fact become the best part of the show. And that show never ends.
