The Great Dust Devil Derby

An unexpected race fell into the laps of the Lincoln Street gang while at Billy's uncle restaurant. Though reluctant, they decided to undertake the impossible. It was a race against time, the desert and experience. How would they build the soapbox derby car in a few of weeks with regulation standards and practice for the race? Only time would tell if Billy and the gang could do the impossible or would nature throw a surprise twist to the race?
