The title of the novel is the same as that of Momma's plan for their trip to Alabama. While Dad has been getting their car, the Brown Bomber, ready for the road, Momma has been recording all the necessary preparations in a notebook.
Because they cannot be sure they will find accommodations everywhere along the way that will accept black patrons, they plan their overnight stops carefully. Momma wants to be sure they have enough food, as they also are not certain to find welcoming restaurants, so she packs ample amounts of sandwiches. She carefully labels each one so they won't run out and the children won't fight over them. She also packs clothes for the hot weather when they arrive and the few things they need en route.
