The lunch crowd boarded the streetcar at Union Station on a busy Wednesday afternoon. Every seat was taken and people were standing shoulder-to-shoulder. The doors shut, but instead of taking off, the train idled. Four mysterious riders in dress coats and fedoras approached the car. The doors opened again, and, with one uniform step, they boarded the train.
These mysterious travelers were actually dancers. They remained fairly still for the first minute, but as soon as someone signaled for a stop, the dancers broke out in random movements.
