everyone should walk tunnels!! Even if your not painting, i know its harder with the wtc shit, but late at night when your waiting a hour for your train and you know its not coming for another hour- walk to the next station!! Its a whole other world down there, all to yourself. Shit you will never see in the rest of your lifetime, the secret rooms, the old writers that have been down there, its like goin back in time, to see who else has been there walking the same tracks as you. Then you stumble upon one of revs' stories, you take a minute to read it, get some knowlege. You see his shit in the craziest of places, it will all be over soon tho, in a few years they will sensor all the tunnel entrances and put a better lock on the hatches and that whole world will be sealed up forever. Soooo get a job and be a transit worker!!! It will give you opportunites to do things you will never have and all your graff friends will be jealous....
