I spent about six months editing Syrup, not counting the work I did once a publisher picked it up. Most of that time I spent printing out a draft, covering it with corrections, entering those into my computer, and printing it out again.
My main beef with this page seems to have been that the Coca-Cola movie was being treated too much like a film and not an advertisement. You can also see some notes by my wife, Jen (whose handwriting is much neater than mine), and my beloved Beanmaster 2000 line.
This page is pretty typical of what an edited draft looks like. I went through this process maybe five or six times.
