I don't get this notion that graffiti can be "quality" or "better than a blank wall" , and who judges what "quality graffiti is?", this is vandalizing things that are not yours without the owners permission. I have seen a beautiful granite arch bridge near me beautifully and painstakingly constructed by Irish immigrants in 1872 spray painted with all sorts of crap over the last 15 years. Charlie MTA, I agree this is like the end of civilization. But I'm over 65 so what do I know.
