Newscopy: "Smoke from smudge pots swirled around Candlestick Park yesterday as Dr. S. Perkins and his crew from Metronics Associates began testing variable wind currents within the stadium. Above, George Kohler records the smoke patterns with a motion picture camera. At right, Jim Murray sets off a smudge pot in the upper stands. When all the data is in, results will be duplicated on a scale model in a wind tunnel by the Research Foundation at Colorado State College in hopes to finding an answer to the wind problem.".
