It's big and it's bright and it's coming soon to a fair or festival near you.  The Louisiana Department of Agriculture and Forestry has created a rolling billboard to take around the state.  Its purpose is to reach consumers with the message that they should buy Louisiana-grown produce and add more fresh fruits and vegetables to their diets.  At the recent Washington Parish Fair, riders on the float were not throwing beads or doubloons -- they were handing out fresh Louisiana satsumas!  The float was paid for with a grant from the United States Department of Agriculture.
