We're exploring both ends of the transportation spectrum on this week's Travel with Rick Steves. Rick learns about the R-V subculture from Chuck Woodbury, who runs an online site for R-V travel. Chuck says that R-V camping has become a popular way to take the great American roadtrip -- even if the roads are overseas. Also, adventure bicyclist Willie Weir tells us about his most recent bike trip through Northern Thailand and Laos. Whether you've got two wheels or more...join us as we explore travel by bike and by R-V...on the next Travel with Rick Steves.
