The incident which prematurely triggered the blowouts was when Wilson High principal Donald Skinner canceled a student production of Neil Simon's "Barefoot in the Park", citing it as too risqué for a Mexican American audience. Although Wilson was not one of the original three schools intending to walk out, 300 students did so on March 1, 1968. The administration had senior students blockade the main exit, but the students found alternatives, pushing the school entry gates back and forth as other students inside demonstrated by throwing fruit, books and other items over the gate. Police and photographers showed up on the scene, and the students were told to return to class. Some refused, forming sit-ins and rallies. As a symbol of the walkouts, students wore the image of a foot on their clothes.
