It's 1903 when Dr. Horatio Nelson Jackson bets fifty dollars that he can drive a horseless carriage (a car) across the USA, from California to New York, in less than three months. Considering Dr. Jackson doesn't know how to drive, there are no highways yet, and everyone else who's tried the trip has failed, the odds are stacked against him. Still, he hires a bike racer to act as mechanic, and the two set off in Dr. Jackson's car, the Vermont, with their team mascot, Bud the bulldog.

Their trip is far from easy street. The duo must pull the car across streams, drive through deep mud and over rocky terrain, and wait for a stagecoach to bring spare parts. And with no windshield, doors, or a roof, every bump in the road means boingy boingy boingy--until things bounce right out of the car!

Then two more teams start out from California, and the race is on! Can a doctor, a bike racer, and a bulldog make it across the finish line first?
