Crash Courses (S02E06)

Willie and the older boys sneak into a scrapyard to scavenge parts for a bike track they're building for the younger kids. They haul back old pipes, boards, and scrap metal, working together to transform a patch of empty land into a fun, bumpy course. The littles are thrilled when they see the finished track, and the whole neighborhood gathers to watch them race, laughing and cheering as they ride.
