From Joe Carducci's new history of the SST era:

"In the van Black Flag threw empty coffee cups and orange juice bottles down onto the rocker panels; when they stopped somewhere they simply kicked the garbage into the street. Trashing? Graffiti-ing? Postering? Pissing? Los Angeles seemed the fallen dream of generations of transplants; the locals, now acclimated to its harsh scape didn't see the point in taking care of it. It took care of itself. It just was. And this was quite unlike other cities. It was part of what make punks in the rest of the country feel like naïve goo-goo hippies when the L.A. bands rolled up."
