we organized the mural, got a whole bunch of graff and mural artists to participate as well as over 30+ young folks to paint, was a summer project last year, my boy trigger lead the project - the old mural was sick and had history, unfortunate that the city and land owners decided to paint over it because the "residents" were complaining about how it made their buildings look.. bullshit, so we petitioned and were granted to re-do a mural there after they spent thousands on making it into a gated parking lot.
