Most graffiti artists shun broad daylight – but not in Clarion Alley, SF's open-air street-art showcase. You'll spot artists touching up pieces and making new ones, with the full consent of neighbors and Clarion Alley Collective's curators. Only a few pieces survive for years, such as Megan Wilson's daisy-covered Tax the Rich or Jet Martinez' glimpse of Clarion Alley inside a forest spirit. Incontinent art critics often take over the alley's eastern end – pee-eew! – so topical murals usually go up on the western end.
