The crowd began forming at Juniper and Filbert streets around 3:30 pm as set-up was still underway. As school let out, high school students from over 25 schools across the city began making their way downtown. Each new group made the size of the gathering swell until the crowd spilled into Filbert street and it had to be closed to traffic. Dozens of students from Sayre, Bok, Furness, South Philadelphia, Kensington, Paul Robeson, CAPA, West, Bodine, Edison, Sankofa Freedom Academy, and other schools began to converge from all directions.
