People love road trips. Some like 'em more than others. And some like them perhaps a little bit too much. This interactive map from Richard Kreitner and Steven Melendez crams the locations mentioned in twelve road-tripping books including Mark Twain's Roughing It and Jack Kerouac's On the Road. That total's 1,500 entries, paired with the most appropriate coordinates the author could assign. You might take issue with some of the book choices, but we'll only accept complaints after you've tackled the entirety of this cartographic labor of love. You'll find the bibliography after the break.
