This week, we continue our discussion with award-winning author Earl Swift about his book The Big Roads. He'll be telling us about the impending crisis befalling America's interstate highway system and the challenges of maintaining a huge system of expressways, sharing the story of how American roads have changed over the past 100 years. Our weekly travel segment Along the Way... visits the desert resort cities of Riverside County, California. Dave’s comedy bit On the Lighter Side goes back on the road for another interview. Plus, join us for all the latest travel news, including lots of talk about the recently marooned cruise ship Triumph, as well as more vintage radio commercials From the Archive.
