retirement from North American Aviation in 1978. He died in 2008. In 2003, Pack 713 celebrated the 50th Pinewood Derby along with Packs 287, 759, 275, and former Cub Scouts from the 1953 Pack 280c. A shoulder patch for the Western Los Angeles County Council that depicted a pinewood derby car and a message of honor to Murphy was released to celebrate the 50th anniversary of the event. In 1980, the design of the block was changed from a cutout block, consistent with a 1940s style front-engined Indy 500 car, to a rectangular block. The tires were also changed from narrow, hard plastic, to wider "slicks." In May 2005, the Boy Scouts of America registered Pinewood Derby as an official trademark. On May 28, 2018, the City of Manhattan Beach, CA held a 65th Anniversary Pinewood Derby Day at the original Scout House (the very place the first Boy Scout PWD race was held in 1953). There were three 35 ft tracks and all cars competing were required to meet official BSA rules. “Pinus Ferrari”, built by Henry M. Caroselli, set Fast Time of Day of 2.501 sec. This fundraising event was well attended (nostalgically, even a few participants showed up with their over-60-year-old cars), with all proceeds going to support the building of a new Senior and Scout Community Center. Construction When using a kit sold through Boy Scouts of America (BSA), the Scout begins with a block of wood, four plastic wheels, and four nails for axles. The finished car must use all nine pieces, must not exceed a certain weight (usually five ounces (150 grams)), must not exceed a certain width (usually 2-3/4 inches (7 cm)) and length (usually 7 inches (17.8 cm)) and must fit on the track used by that particular Scout pack. Blocks can be whittled with a hand knife, bandsaw, or a carving tool. Other than the previous basic design rules, the Cub Scout is able to carve and decorate the car as he or she chooses. Cars vary from unfinished blocks to whimsical objects, to accurate replicas of actual cars. Weights can be added to the final design to bring the car to the maximum allowable weight. A high-density metal weight, such as tungsten carbide which is not toxic like lead, reduces the volume of wood, which reduces air friction and increases speed. Axle friction can be reduced by polishing the nails
