At 15:00 Pacific time, a Piper PA-25-260 struck a fence while trying to tow a glider from a dirt field. The pilot was not injured. The glider had made a precautionary landing in the field when the pilot reported losing lift. He contacted a local soaring club and requested an aero-tow out of the field. The Pawnee pilot paced off 1,600 feet, which he calculated would be enough for the airplane and glider to take off. When the tow plane struck the fence, the glider released, cleared the tow plane by 2 to 4 feet, traveled across a road and collided with another fence. The glider pilot was also uninjured.
