WHILE RETURNING TO THE PRIVATE AIRSTRIP, THE PILOT WAS UNABLE TO MAINTAIN THERMAL LIFT AND DECIDED TO MAKE A LANDING ON A DIRT ROAD. DURING THE LANDING ROLL, THE RIGHT WINGSTRIP STRUCK HIGH VEGETATION, CAUSING THE GLIDER TO PIVOT TO THE RIGHT INTO UNEVEN TERRAIN. THE RIGHT WING AND EMPENNAGE WERE DAMAGED.
