Rick Steves Podcasts

I've been listening off and on to Rick Steves podcasts. Today, MK and I went for a ride NE of Austin, and I listened to one on "Outside Budapest", and another on "Berlin: Then and Now".  Guest was an American ex-pat living in Berlin who did walking tours. Sounded good, but I'm not sure we'll be able to work Berlin in the schedule if we're driving. Not a convenient way we can do that that I've figured out.
