In March 1975, approximately 2,000 people from California to Canada descended upon Palm Springs to celebrate their recreation of choice — square dancing. Local resident and 20-year veteran square-dance caller Osa Mathews was on hand to command the couples to do-si-do and box the gnat. During the event, 1,000 couples broke in the enormous maple wood dance floor at the Pavilion in the new Sunrise Park, which turned 50 this year.
