Today we explore the epic melee that is cardboard tube fighting. The Cardboard Tube Fighting League will hold a cardboard tube fight in San Francisco this Saturday on September 17th, the year 2011, 11:30 to 4 in the afternoon, at the Hayes Valley Farm.
Enter the cardboard costume contest. Cardboard wrapping-paper tubes will be provided. Fight 'til the last tube is standing (not bent). Just think: you and hundreds of cardboard-clad hipsters, duking it out in a cardboard tube frenzy.
The memorable cardboard-tube battle of 2008 - Dolores Park, San Francisco.
Cardboard - packaging material, rooted in violence.
