When asked what was the secret of a fast car, 6-year-old Jeet Kalsi replied, "I have no clue," despite taking first place in the championship race of the Pack 10 Cub Scouts pinewood derby Saturday. But his mother was quick to correct him. "What's the secret?" she asked. "From your grandpa, from your dad, from your mom and six visits to the hardware store," his mother, Sheila Kalsi, said. Zach Kozlowski, 6, and his father, Paul, of Burr Ridge put their effort into building a car with no time to spare.
