"One of the things that has struck me occasionally about graffiti is that - except for the relatively rare full word - it is impossible to tell whether it came from North or South America, England, France, Germany, Greece, Scandinavia ...

I agree! I have seen graffiti from California to Budapest, and it is always slavishly, tediously the same.

It's often in places that were dangerous to be in.

Why are we producing so many youths that seem to have no intelligence?
