It's been almost 50 years since Arthur Frommer (FROE-mer) first published his groundbreaking travel guidebook "Europe on Five Dollars a Day." In the 1970s, Frommer's books helped instruct a young Rick Steves how to travel light, on a tight budget, and "through the back door" to interact with the people and authentic cultures overseas. Arthur Frommer is Rick's special guest on this week's edition of Travel with Rick Steves, as they reminisce and chat about how much international travel has changed over the past half-century.
