Thanks, Dave!
I will point out that the article perpetuates the nonsense that he wrote the first draft on a roll of paper in 3 weeks; he wrote, rewrote, changed the subject, rewrote again, changed the subject back, rewrote, etc., etc., over years - 6, IIRC.
He habitually used a roll of teletype (not, as I always heard, butcher's) paper not so he could crank out a novel in one long speed* run, but because he typed 100 wpm, and changing sheets took longer than typing them.
*Yes, almost everything he wrote was done under the influence of amphetamines; he might not have written On The Road in one fell swoop, but he did write fast, in long swaths.
