Some sheltered, stuck-up and conservative people think that graffiti signals the downfall of urban centers. In my opinion I think graffiti represents the antithesis of urban decay. In any major city in the world you're going to find graffiti -- It is a sign of life. Graffiti, just like any other art, is a form of expression. It can be politically powerful, funny, ominous, angry, sad, personal or beautifully repulsive. It portrays a vibrant city with an active soul. Graffiti means that people are on the streets and actually interact with the city they live in. I always find it relieving to see good graffiti abound. It's like being in a museum, some of the works you like, some you don't. Cities would be completely dull and lifeless without graffiti, trust me.
