Photographer Joel Meyerowitz decided to go on a last big trip with his father Hy, who has Alzheimer's. Joel also brought his own son. The purpose of the trip? To try to get close to a part of Hy's personality that Alzheimer's has eradicated and see if it might be possible to jumpstart some of his memories. Joel and his son decide to make a movie of the trip. We hear some of the very funny, very moving raw footage. The film, Pop, aired on the PBS program Frontline. (24 minutes)
