Carol should be able to point you in the right direction. Once upon a time, she posted a link to the first draft of the pilot. It was very . . . different. Completely lacking in the urban legend angle of the show. Dean was, iirc, harder. And, as I remember, a rather unpleasant character. I'd have to re-read, though, because I remember thinking, "Wow. I'm glad they made the changes they did. This would have been a completely different show."

I also remember scene that I thought was really cool. It took place at night, in a corn field.

Carol? Might you post the link to your LJ again?
