The Tulane Green Club bops across the uptown campus during a "Second Line for Sustainability" on Sunday (Oct. 7). The march was powered by music from members of the Tulane Brass Band. 

In step with the music (from left) is Green Club member Celia Horowitz, with Nick Stracco, club president, and Susannah Halbrook, vice president of finance.

As the second line winds down, Green Club members break into a dance on the Lavin-Bernick Center Quad.
