I know, I know, I don't "get it", too old, etc. All of us in this hobby are artists to some degree, and I can appreciate the talents involved, but to me, it begs the question of why not put it on canvas instead of other people's property. And yes, I've heard the story about how putting it out on public display is integral to the art, a commentary on the dark side of urban life for youth, yadda, yadda, yadda.
And, I can even understand why some modelers put it on their rolling stock - hell, nine out of ten cars on the mixed freights around here are covered in it the stuff. Unit trains seem less likely to suffer from it, I'm guessing because they tend to keep moving.
I don't subscribe to the "hobby is dying" philosophy - I think it's changing, as all things do, over time. But somehow, this seems sad to me, that kids find the graffiti more appealing than the cars.
