The young, uniformed cartoneros caught the attention of passersby in the crowd not only because of the size of the group – 35 – but because of the worker’s uniform they wore for the pilgrimage. It consists of dark blue pants and jackets lined with neon green strips for visibility. It clearly marked them as workers. The members of the MTE stood out for another reason. They conveyed a seriousness that was in contrast to the many of the chatty, smart phone-carrying teenagers. They are young workers, and they seem older than their years.
