Now the New York Times tells us Jack Kerouac did the same, but on a far grander scale.
Almost all his life Jack Kerouac had a hobby that even close friends and fellow Beats like Allen Ginsberg and William S. Burroughs never knew about. He obsessively played a fantasy baseball game of his own invention, charting the exploits of made-up players like Wino Love, Warby Pepper, Heinie Twiett, Phegus Cody and Zagg Parker, who toiled on imaginary teams named either for cars (the Pittsburgh Plymouths and New York Chevvies, for example) or for colors (the Boston Grays and Cincinnati Blacks).
He collected their stats, analyzed their performances and, as a teenager, when he played most ardently, wrote about them in homemade newsletters and broadsides. He even covered financial news and imaginary contract disputes. During those same teenage years, he also ran a fantasy horse-racing circuit, complete with illustrated tout sheets and racing reports. He created imaginary owners, imaginary jockeys, imaginary track conditions.
