I have started working on my graphic novel again, although a big book project involving kids and dinosaurs might put it on the back burner again. Anyways, developing such a long story is a daunting task. One of the things that helped me immensely is a piece on screenwriting that Bruce Campbell has on his website. I'm posting the link because I got a lot out of it. He succinctly delineated the important aspects of writing a story better than anything else I've read. I think it can be applied to any form of writing.

I'm a big Brisco County, Jr. fan.
