Long before Jack Kerouac penned his famous American roadtrip epic, Sinclair Lewis wrote what may in fact be the seminal work of the genre. This cheerful little road novel, published in 1919, is about Claire Boltwood, who, in the early days of the 20th century, travels by automobile from New York City to the Pacific Northwest, where she falls in love with a nice, down-to-earth young man and gives up her snobbish Estate.
