text_A: After spending two weeks in Vernon, Morris returned to Berkeley and began working on a script for a work of fiction that he called "Nub City". After a few unproductive days, he happened to read a headline in the "San Francisco Chronicle" that read, "450 Dead Pets Going To Napa Valley". Morris left for Napa Valley and began working on the film that would become his first feature, "Gates of Heaven", which premiered in 1978. Herzog had said he would eat his shoe if Morris completed the documentary. After the film premiered, Herzog publicly followed through on the bet by cooking and eating his shoe, which was documented in the short film "Werner Herzog Eats His Shoe" by Les Blank.
text_B: Would Morris need a lot of space to store his writings on Nub City when he left for Napa?
NO.
