When the show content is new, this is one of my top five podcasts. I first started listening to it about a year ago, and then downloaded a few dozen of the old shows. His interviews are great, and his travel advice is extremely helpful. The podcast introduced me to the public tv show and the travel guides, which are both fantastic in their own ways.
The one thing to watch out for is re-runs. I understand the Rick has spent a third of his adult life in Europe, so he's on the road a lot, but it's a little frustrating to see a new episode pop up in my itunes, and start listening to, only to realize I've heard this show before. But other than that, this show is perfect if you're at all interested in travel or foreign culture.
