The pinewood derby is a racing event for Cub Scouts in the Boy Scouts
of America. Cub Scouts, with the help of parents, build their own cars
from wood, usually from kits containing a block of pine, plastic wheels
and metal axles. With the popularity of the pinewood derby, other
organizations have developed similar events, and a small industry has
developed to provide tracks, timers, scales and other products.
