Jane and Jerry weren’t the first to come here for their own purposes. Most of the horns were lavishly stenciled with bullet holes, some old, some new. A structure-hit gang had tagged the tower blockhouses with much-faded graffiti. Old-fashioned psycho-radical slogans like SMASH THE BALLOT MARKET and LET THEM EAT DATA and SCREAMING WOLF SURVIVES , done with that kinky urban folk intensity that urban graffiti had once had, before the spirit had suddenly and inexplicably leached out of it and the whole practice of tagging had dried up and gone away.
