Back in the late '90s and early 2000s, San Francisco - in particular the Mission and the Tenderloin - was home to a tight underground network of graffiti writers, skaters, punks, bike messengers and bartenders. The nightlife back then was grimy and hedonistic; driven by a near-universal idea that ill-advised behavior would yield zero negative consequences. It was a world of brawls, bloody accidents and flagrant law breaking - and it was captured in its debaucherous entirety by the camera of street photographer Dave Schubert. On January 5, Schubert died suddenly at the age of 49.
