Keep Blanco Beautiful is on a campaign to spruce up the community and tackle refuse as the annual "Don't Mess with Texas Trash-Off" returns. It is all part of "The Great American Clean Up" which is held annually from March 1-May 31. The clean up is the nation's largest community improvement plan, said KBB's Retta Martin. "KBB will partner with the City of Blanco on April 18 for the 16th annual city wide cleanup and ninth annual Blanco River cleanup,"
