Here we go, label them all chavs because they're teenagers who DON'T have the same interests as you lot. Not being funny but I wouldn't class them as chavs, all I'll say is at least they're not standing on street corners and bus stops getting gurned up and attacking members of the public, they're doing something with their time, as controversial as it may be.
Now time to watch me get slated
I speak to a graf. artist from London on MSN (got to know him through other means, he only mentioned it one day and I found it quite interesting). He knows a few of the notorious NT crew, and they all seem sound - not the typical vandals, they see it as "art". I don't share the same view tbh, but he is a really interesting geezer to chat with, got some stories to tell.
BTW - the comments left on that youtube video - I *really* don't think they'll care what class of train it is, can't really see them thinking "oh noes, we got the class number wrong, what are we doing we should stop this at once"
Fair play for speaking out though.
