Two men and a dog set off on the first transcontinental car trip in this fetching re-creation of a true story. Responding to a $50 bet, Horatio Jackson hires a mechanic, buys a 20-horsepower Winton (this was 1903) and sets out from San Francisco, acquiring a bulldog along the way. Considering that there were but 150 miles of paved road in the whole country at the time—and neither gas stations nor many road signs—their 5,600-mile journey to New York, accomplished in just 63.5 days, stands as a triumph of sheer perseverance. In his cartoon pictures Hargis depicts all three of his goggle-wearing travelers having the time of their lives, determinedly riding their increasingly mud-spattered horseless carriage through mountains, deserts and storms. The author sticks closely to the historical record in her present-tense narrative and layers in more detail, plus photos, in a closing note. Though she doesn’t fill in all the blanks—where, for instance, did they find gas and spare parts?—her invitation to clamber aboard will be hard to resist. (Informational picture book. 7-9)
