Racing in a Cub Scout derby is great fun. You'll get to design your racing vehicle, work with a parent to build it, and see it perform on race day. Win or lose, you'll take pride in having done your best. When you race in a Cub Scout derby, you learn craft skills, the rules of fair play, and good sportsmanship—things you will remember all your life. The pinewood derby is one of the most popular and successful family activities in Cub Scouting. Pinewood derby cars are small wooden models that Cub Scouts make with help from their families. Then they race the cars in competition. The cars are powered by gravity and run down a track. Most packs have a pinewood derby every year. It can be run indoors or outdoors. Every boy can design and build his own "grand prix" car to enter in the race.
