It was all about speed Saturday at Phil Moore Park during the final day of the National Derby Rallies, an event similar to a soap box derby.
Dozens of soap box derby cars and drivers came to the area from 22 states to see who could be the fastest.
But it wasn't just cars and drivers at this event, organizers say the sport in a family affair.
"The important thing about our organization and soap box derby in general is the fact that it is a family oriented sport. You don't drop your children off here, you stay here as a family and that's what is unique about our sport," says Todd Garloff from the National Derby Rallies Association.
The families and their cars have been in the area for a week now and say Southern Kentucky has been a great host for the championships.
