As shoppers pined for Black Friday bargains, the halls of the Pikes Peak Center hummed with activity.With mere hours until opening night of "The Nutcracker," there was much work to be done. The holiday classic featuring the Colorado Springs Philharmonic, Oklahoma City Ballet, Colorado Springs Children's Chorale and local dancers runs through Sunday.Young girls with rouged cheeks and hair tightly wound up in buns scurried through back hallways as orchestra members practiced passages of music from the concert pit.
