A trip to the hometown of the actor’s son

Forty years ago this summer, Andrew McCarthy made his screen debut in the movie “Class,” and went on to massive fame as a member of the famed “Brat Pack” group of young actors in films like “Pretty in Pink,” “St. Elmo’s Fire” and “Less than Zero.” Then in the 1990s, his life expanded when he walked solo on the Camino de Santiago, the historic and grueling pilgrim’s trail that spans 500 miles from Southern France to the western coast of Spain. That experience led to McCarthy’s second career as a writer. He became an award-winning travel journalist and the author of three New York Times best-selling books: “Brat: An ‘80s Story,” “Just Fly Away” and “The Longest Way Home.”
