It's Saturday, October 18; our last morning in Athens before our road trip around the Peloponnese. And what's a road trip without snacks? In Athens the go-to bakery is 72 Hours -- named for the time it takes for the sourdough starter to proof. The line at the take-out window  is long but moving fast and we have the pleasure of watching the bakers ply their craft through the windows as we wait.
