During the "hippy days" of the 1970s, Carl Franz and Lorena Havens made a habit of driving from Washington state to Mexico in a VW van. The couple, who still spends the better part of each year exploring the back roads and magnetic appeal of Mexico, join Rick to help explain the appealing Mexican culture. Their classic guide book, "The People's Guide to Mexico," reads like an adventure manifesto, and has recently been updated in its 13th edition.
