Years ago, Chevrolet admonished Americans to See the USA in a Chevrolet. It's unlikely the men who dreamed up that advertising tagline-and the song, often sung by Dinah Shore-expected people to take an automobile trip through all 48 contiguous states, but three young road-trippers recently did just that. (Too young to remember that ad campaign, they did it in a Scion xB.)

Displaying an iron will that exceeds even the most hard-charging Clark Griswold, they did the whole thing non-stop, in just under 107 hours. Check out their route, and their blog, at www.greatamericanroadtrip.us
