Studying these photos that Michael Luckenbach sent in we see that this is tagging not gang graffiti. But still these scrawlings are unwelcome at the newly renovated Howard "L". These territorial pissings are on the Evanston side of the "L" station.
These pics are being sent on to this email address firstname.lastname@example.org for the cops and here for the alderman's office email@example.com (this blog post discussed where to send graffiti pics so that they are removed and studied, but its always good to have a refresher).
