Pinewood Derby

 
Pinewood Derby racing season is just around the corner and this year the Y is inviting kids of all ages to join in the fun!
 
The pinewood derby is a racing event for unpowered, unmanned miniature cars. About a month before the race, racers build their own cars from kits containing a block of pine wood, plastic wheels, and metal axles. On the day of the race, cars are weighed, and then raced on tracks provided with timers. The fastest cars win! Traditionally, pinewood derbies are run by chapters of the Cub Scouts program of Boy Scouts of America. However, the Y is inviting all kids to race here - non-Scouts are welcome as are Scouts who have aged out of the Scouting program.
 
The Y will have three classes for racing:
Open Class Youth: 14 and under
Open Class Adult: 15 and older
Vintage Class: The Vintage Class is for former Cub Scouts who still have their pinewood derby cars. Vintage Class cars are not subject to the regular pinewood derby rules other than those that affect the ability to clear starting gate (height) and sensors (no weight extending below the body of the car).
 
Winners of each division will receive a trophy.
