I read this in 5th grade, and still have it.
3 guys (Wally, Link and Injun) who jut graduated Alhambra high school in LA, and have an endurance run contest against some classmates with a '54 Ford hot rod, with a Packard that they pull out of a chicken barn in Lancaster.
The rally is from their high school parking lot, through San Francisco, to Portland. A lot of problems for the 3 guys with the Packard, just to get it running, keep it moving, and make the journey with weather, roads, and old car problems. They only get 150 dollars to make the trip, and when money runs out, they have to get jobs along the way, like golf caddying, to make some cash for tires, repairs, gas, and food.
A person who reads alot will whip through this in one or two sittings, because it's riveting and keeps you fixed on what's next.
