Lindsay and Viall participate in a second line parade, which is a historical tradition in New Orleans. It generally consists of a brass band and the "main line" or "first line" is the main part of the parade. Those who follow the band to dance or just to enjoy the music are called the "second line." That's where the name comes from. In the French Quarter of New Orleans, these parades generally take place on Sunday afternoons. (ABC/Mark Coffey)
