Since I didn't have a pen, I think I wrote with the charcoal and the graphite pencil as much as I sketched. I jotted down notes and especially key referential words. This won't account for a new scene, but it will help round out and especially solidify scenes, although I think one scene--the hurricane--will especially benefit from this exercise.
I got the same kind of artistic jolt last week when I took the day off and photographed some back roads. Just cleared myself of words and I opened myself up to new sources of inspiration. And then suddenly the words started flowing again.
