If you go to the corner of Hooper Street and Dukes Boulevard (the western junction) you'll see a building with graffiti covering its lower portion - wrapped all the way around. If you get closer you should recognize El Burro, Misty and Kengo (among others) tagged on the wall. If you need help visually from afar, just look for the big words "VICE SQUAD". Also on this wall are the helicopters depicted on the cover of Vice City.
