I totaly agree with you, there are alot of these "new" riders who like you say, have t-pros and t-birds who just don't give a sh*t abou the places thy ride and just generaly show no respect, it realy does my head in, i was riding with some of these riders a while back and was trying a tap and hit my bash, not liking this i decided to leave it, the kids then went on about how the wall was not mine sh why should i give a fook, to which i replied with abit of a mega lecture. It does realy do my head in, fortunatly when i am at home (cornwall) riding rocks there is nothing like this to worry me Adam
