Ballroom dancing is making a comeback on university campuses around the country. What was an English art form, a finishing school requirement and a wedding couple's moment in the sunshine has burst into a college craze. About 17,000 students at 120 schools are doing the waltz, cha-cha and swing, according to figures provided by the United States Amateur Ballroom Dancers Association. At UC Davis, more than 50 students gather each Sunday evening in the South Silo area of the campus to dance the rumba and other traditional numbers that showcase their love for ballroom dancing. "This type of dancing combines art, romance and beauty," says Ali Yedes, student coordinator of the dance club. "It's also a return to elegance, courtesy and civility." For a lot of the participants, ballroom dancing is replacing slam dancing offered in nightclubs. The UC Davis dance club provides instruction for people of all dance skill levels and is open to anyone.
