An area man's aggression toward the Longhorn State was curbed Sunday after he read a bumper sticker that warned, 'Don't Mess With Texas.' The incident escalated after Joplin resident Jake Vretnar, 31, swore to friends in a drunken tirade that he would 'go and fuck up that state.' Vretnar boarded his truck for the drive, but cut his trip short upon seeing the bumper sticker. 'I guess they're serious,' he said.
