Have bike, have GoPro, will ride. A fun video from a fun event - Critical Mass through the streets of Joburg on 25 January 2013. From Facebook: "Critical Mass is NOT a race. The CM movement aims to raise awareness about the viability of bicycles as a form of transport; the cyclist's right to share public space safely and the need for cycling infrastructure. Critical Mass Joburg aims to bring more people back into the city. CM is about having fun, in a group, on wheels." Video by Michael Salzwedel. Crazy song is Essa tal de tequila by Velhas Virgens.
