Ellie White, 7, of Mancos, swings around the dance floor during the contra dance at Park Elementary School. White attended the dance with her father, Tim White. Organizer Wendy Graham said contra dancing is similar to square dancing: It employs a live band and a caller to teach the dances and then prompt the dancers. However, while square dancers remain in the same square, couples in a contra dance face each other in long lines and progress up and down the lines, dancing with new people as they go. In contra dancing, the culture is to switch around, Graham said.
