756 Resurrecting Roman Rubble; Plovdiv, Bulgaria; European Travel Serendipity

A self-described "Rome nerd" helps us picture what it was like to live in the Roman Empire and explains how much we can learn about the era from its now 2,000-year-old rubble. Then a tour guide from Bulgaria sings the praises of its cultural capital, Plovdiv — one of the oldest cities in Europe, possibly in the whole world. And listeners share serendipitous stories from their European travels.
