Arguably Houston's unofficial motto, and definitely its most famous two-word slogan sprayed on the side of a rusting railroad bridge, "Be Someone" is, at its core, an invitation. Certainly a number of citizens have taken it upon themselves to alter the five-year-old graffiti from time to time — once to "Be Football," just in time for Super Bowl LI — but, thanks to anonymous neighbors, never for very long. Speaking to the Bayou City's wildcatter past and individualistic self-image, this singularly public-spirited vandalism has since made its way onto T-shirts and, as of this past St. Patrick's Day, H-Town rapper Paul Wall's chest. "I get inspired every time I drive thru downtown and see it sprayed on the bridge," he informed his Instagram followers. Visible just north of the Milam Street downtown exit, "Be Someone" could well be inspiring someone stuck on I-45 south right now.
