I’ve driven under this railroad overpass a hundred times over the past few years. Each time I pass under this immense piece of graffiti I wonder what it means, what it stands for. After finding multiple definitions of the word, I kind of liked this one, “form of visual communication, usually illegal.”
Update July 17, 2015: A visitor to this blog (cadillacacac) let me know that Gruvenberger was/is a rock band out of nearby Rock Creek and that the band has a Facebook page. Thanks !!!
