Cuba was in the news this week as President Obama announced he was restoring diplomatic relations after more than 50 years of a lingering Cold War policy. That could be on the mind of a leading ballerina as she performs in the holiday classic "The Nutcracker" ballet this weekend. For the last 15 years, principal dancer Lorena Feijoo has had starring roles as the snow queen and sugar plum fairy. Feijoo grew up dancing with the National Ballet of Cuba. We caught up with her as she rehearsed with Ballet Master Christopher Stowell at the San Francisco Ballet studios.
