Part three of the Day to Day series on marriage education profiles a traveling conference called SmartMarriages. A diverse collection of people have devoted their careers to teaching people how to have a successful marriage.
Conference attendees, however, must wade through booths where marriage advocates have very different ideologies and approaches. Some see marriage and divorce as a public health issue, but others emphasize religion -- primarily Christianity -- as the key to a healthy, successful union.
Still, liberals and conservatives alike agree on one thing: marriage is more than a simple piece of paper, it's an institution that needs to be preserved.
