The Pinewood Derby event is a tribe favorite. All the tribes race against each other, and the top cars from each tribe race against the top cars from other tribes to determine an overall winner (both individually and tribe).
The Dads, I mean sons, build the cars from the same kits, adhering to the nations rules. There has also been a cheaters classification, as well as a siblings classification.
In past years, there has also been additional entertainment in the form of race tracks, bounce houses, and BMX bike demonstrations.
